Giles weather station — sited next to almost the only bitumen for 500 km

I visited the famous Giles weather station a couple of weeks ago. It’s an ACORN top ranking site, it even has a Met office. Because it so central and so remote the measurements here are used to estimate temperatures across a vast area — indeed, arguably, it’s the most influential site in terms of Australia’s area-averaged temperature. It’s 1,700km drive from Perth (1,000 miles) and the last 800 km of that is dirt road with wild camels. It’s so remote the nearest post box is 340 km away across the state border at Uluru / Ayers Rock.

This could have been the best site in Australia, unaffected by UHI, open since 1956, staffed with professionals.

Despite the site being surrounded by three deserts and 500,000 square kilometers of wilderness somehow the only short stretch of bitumen for miles starts 600m from Giles and runs within 10m of the Stevenson screen.

Giles is arguably the most central and most remote station in Australia.

Never fear, civilization is here:

Stepping back — the site is surrounded by gravel:

There is even a kind of gravel car park beside the site. Not that there are that many cars. |  Click to enlarge.

 

The quest remains to find one good long running site in Australia.

Ken Stewart gives Giles Met Station a Fail.

By the Bureau of Meteorology’s own standards the site is non-compliant.

The screen is surrounded by an extensive area of graded bare gravel, unlike the environment it is supposed to represent, (buffel grass, spinnifex, and low scrub). Bitumen was laid on the road between September 2011 and October 2012 and is less than 30 metres from the screen. 30 metres is exactly how far a [6m wide sealed] surface should be. The bare gravel surface right beside the screen is the main problem.

The BOM knows this of course, in excruciating detail. The road was sealed around 2011. This is all marked up on  the BOM site info. Presumably, they’ve “corrected” for the road using sites a thousand kilometers away?

There’s a thousand square kilometers of better spots in every direction.

    Is Giles still manned? I thought it had been switched to automatic operation?

    Still, an example of poor management by the BoM. It seems they don’t care about the actual reading because they will adjust it anyway.
    Ken’s Kingdom is well worth a visit if you still have delusions that even the raw temperatures are worthwhile.

      Ken’s done a great job
      And he’s been doing it since July
      Checking every BOM weather station.
      So far 175 non compliant stations
      Out of 720..
      A significant fail rate !
      And enough to say
      That the Basic Observations made by the BOM are wrong !

          Thermal camera imaging would reveal a temperature differential between the unpainted steel pipe ( it could be called a ‘heat pipe’ lol) and associated steel base (The steel base could be called a ‘sandwich toaster plate’ lol) and the Giles Stevenson’s screen on top of it on a sunny day.

          A real serious bit of apparatus/kit.

            “how the screen is insulated from the steel structure it sits on”
            Insulated? Looks positively encouraged instead. Look closely at the floor of the screen at this link. It is three east west slats. The two at the front and back are lower than the large center one leaving a very open air path up. This would obviously allow air to flow directly up off the pole. It could well be the main air flow when there is no breeze. It would take a very special kind of logic to think that would have no effect. https://upload.wikimedia.org/wikipedia/commons/f/f2/Interior_of_a_stevenson_screen_at_the_Darwin_Met_Office.jpg

            I wonder if the BoM have done any comparative studies between Stevenson screens with white wooden legs and ones with steel poles? A quick little 40 year long study should do.

              All these sites (even if they read properly) really only show whats going on in a local environment, at the ground, not on a global scale or even trends. The only more useful measurement would be a proper atmospheric profile by weather balloon, even then it is local.

          E S You are wrong on this point.
          I thought so at the time your wrote it
          But have only now found the evidence
          To show you wrong.
          Here is a BOM video
          To ensure their weather stations are ”accurate ‘!
          https://www.youtube.com/watch?v=-qQHDGA7SsAon Youtube about the guidelines it uses
          Thye are the guidelines that Ken has used for his examination process.

          Ummmmm ?

          But take a look at the video..
          It shows the inside of the stevenson screens
          There is no metal plate..

          Interesting !

            In an electric toaster the heating “plate” is the bit with thin wires wrapped around it and is usually vertical.
            ES has not described the floor as being metal. This is something you seem to have mistakenly attributed to him. Rather as “the steel structure”, “Steel base” or “radiator” that sits on top of the pole but below the box. Remember car radiators work via convection.

            It can be seen in the picture above. No need to go to YouTube…yet. It is there as clear as day.

            If you consider those four letters above to be a drawing it is the “Y”. Nowt 0.45 into the video you posted it is the single most obvious thing below the box. The floor of the screen at 0.45 can also be seen to have a gap in it between the three slats. That gap would let the hot air flow up from that “toaster” element to the inside of the screen.

            Yes Peter
            There is a generation which has a morbid fear of Facebook and the Social media
            I used to be one of them myself til last year.
            However if we want to have an impact on the younger generation
            We need to be in their ‘Social Media ” space !
            So I have set up this group.
            And anyone can read what’s there.
            But if you wish to comment
            You do need to join the group.

            The joining process actually allows
            Screening out of the idiots.
            And those being abusive
            Can be booted as well.
            It actually makes for a more peaceful process
            Than even here on JoNova.

    The site may not be representative of the land around it, but is the land around it representative and for what distance? And to what accuracy? These are questions not addressed. As previously proposed we would learn a great deal from a matrix of sites over a few km to see if the averages are reasonable even over a small area.

    I agree with those scientists who think a manufactured and weighted world single average temperature over the globe, equator to poles, night and day, winter and summer is a nearly meaningless number in physics. It is an indication at best but cannot be worked backwards into anything meaningful. This is an important problem when the IPCC are claiming a world record temperatures by 0.004C.

    To me that is not a world record, it is the same temperature to two decimal places. This is in itself quite suspicious, possibly as if it has been fine tuned to be larger and that is politically important for ongoing funding. Adding up a lot of wrong numbers does not increase accuracy because what you are measuring has an intrinsic error. If every part of the world is identical year to year, what is going on? Similarly if they are all quite different but add up to exactly the same number, how did that happen? Smells like Roquefort.

    Consider the rainfall prediction by the BOM for Melbourne today. 1-2mm. In the West of Melbourne, rainfall 0mm. In the East, rainfall 3mm. A distance of 20km. Now you could say that the average was spot on but in fact it was 100% wrong in both locations.

    Long distance averaging is nonsense because variations can be great over even small distances. From one side of the paddock to the other. Then wind and cloud and evaporation and shadow and soil type and colour and vegetation and depressions etc.

    Then you have to wonder why they bother with land measurements in the satellite era. Or if they were serious why not use an array of a million transponders, solar powered and able to be read from satellites. What happens is that the custodians of data are preserving and modernising something which is in principle obsolete. A bit like SBS, multi language TV from the 1970s in the internet age. Or the ABC a hundred years later when they are so openly biased and so undeserving of more than a billion dollars a year for their opinions not facts.

    But the real problem is whether the land temperature data is meaningful to 0.001 simply because that is the reading accuracy. I would suggest temperature variations even over a short distance would be lucky to be representative to within 1C of the large area allocated to the instrument and this is the amount of the warming alleged. And a million wrong measurements does not make it any better. It’s not that the world is not warming, its that announcing a manufactured world temperature is a rough indication at best. As to altering the temperature data to fit the models, that is a science crime.

      It’s not that the world is not warming…

      You lost me there.
      Tony Heller presents original unadjusted NASA/NOAA data that demonstrates clearly it is not.
      Furthermore: Temperature readings from 2005 (far left) to the present (far right) show absolutely no warming.NOAA USCRN

      There has been no warming in the United States since at least 2005, according to updated data from the National Oceanic and Atmospheric Administration (NOAA). U.S. Climate Reference Network (USCRN) includes 114 pristinely maintained temperature stations spaced relatively uniformly across the lower 48 states. Strikingly, as shown in the graph below, USCRN temperature stations show no warming since 2005 when the network went online. If anything, U.S. temperatures are now slightly cooler than they were 14 years ago.

        I agree. However a slight warming is expected based on the last 2500 years. We are at the top of a curve, where it looks flat but there is a steep slide on the other side. I am a complete convert to the Fourier analysis of Prof Weiss. It is so simple. A single cycle of the sun. Plus the reaction of the one great heat sink, the Pacific Decadal Oscillation. This explains everything and by the principle of Occam’s razor, it is obviously right. CO2 is utterly insignificant.

          It’s a feeling which persists. In the morning, walking the dogs, the day can start at a cold 8C and end at 20C. You feel the strength of the sun on your face. You walk in the sunshine if you can. It is so obvious that the sun is the giver of life and heat to the planet and when you consider that the 12C change is entirely from the sun rising, you know that the sun is the main driver of warmth. Not greenhouse gases. After all, CO2 is constant winter and summer, year after year and in a single day cannot contribute a thing. Clouds on the other hand can change the day completely. A cloudy night is much warmer, like a blanket. So unlike a clear freezing desert sky. The difference is water, not CO2.

          So you instinctively know CO2 is irrelevant. Every day is a CO2 cloudy day. Constant. Increasing 0.5% each year in cloudiness. And if I have to offer an opinion, the days are far cooler now than in my childhood, despite ‘climate science’ and the BOM and Acorn. I do remember a summer 30 years ago when 28 out of 31 days in January were over 30 degrees. I went to the beach every day. It is a great and happy memory. Not such a summer since.

          The seas are not rising, I would have noticed. The summers are not warming and I would have noticed. They are cooler. And droughts and floods are the climate, not climate change. And bushfires are caused by the Greens. And the traffic problems as they shut down the city. Most people cannot ride a bicycle to work, but the Greens think otherwise.

      Given that the approximate habitable areas on the Planet are about 15°C the record breaking margin you mention, 0.004C°, can be seen in another light.

      Say the new record is 15.004°C, this implies working to five significant figures and is obviously not measurable with a mercury thermometer.

      In the real world we work with four significant figures and even that level of reporting is not justifiable when reporting atmospheric temperatures.

      As you say, claiming a record on the basis of the “immeasurable” 0.004 C° is a fantasy.

    Another key fact here that Ken keeps track of is the % of stations which are non compliant of those surveyed. Its been climbing steadily and is now over 23%.

    The BOM is a complete joke.

    I work in the food industry and audit plants. This level of non compliance would not be tolerated and I have seen managers terminated when high non compliance (like this) is found.

    But for the BOM its situation normal and unsurprisingly the heat favours their slavish support of the failed AGW theory (as we all know) so they make no attempt to correct it. Were the screens set up at the exit of freezers or cold rooms they would be instantly moved…

    They must be aware of Kens work, but I am betting no effort at all has been made to act on what he has found.

    When will the BOM be held to account? Looks like a lot of unaccountable highly paid virtue signallers here…

        I suppose that’s why we don’t mind them making some really outrageous claims even some CAGW followers are sceptical about. It exposes them for that the extremists are; idiots and fools to be scoffed at. Trouble is such wild claims are often unquestioned even by our so called leaders, which lends to the path of giving the extremists too much credibility. We need a real leader with backbone, integrity and honesty, not one who obfuscates and ignores the plight of people who are truly suffering from real issues, such as the farmers and not pretending all is OK and we will meet our targets to sacrifice our economy for nothing.

    To repeat, the idea of the Stevenson Screen was to measure temperature, humidity, amospheric pressure and more as accurately possible at a specific location. It is shielded from ground radiation, elevated, louvres to stop direct sunlight, enough volume and painted to reflect incident light. The big enemy is light and other reflected radiation. There are rules.

    However even if sited perfectly, the idea that a single screen give the same readings as another 20km away is fantasy. And the surface of the planet earth is 510million km2, so a stevenson screen every 20km would require over 1.5 million such screens, 3/4 over water.

    I also note that we have learned so much from ab*rigines. The BOM says this.

    “Australian meteorology originated 40,000 years or more ago with the observations, belief systems and lifestyle of the Aborigines.”

    “Further information on the valuable contribution of Aboriginal culture to the weather knowledge of the Australian climate can be found in our pages on Indig*nous Weather Knowledge.

    The first systematic weather observations in Australia were made by William Dawes, a lieutenant in the Royal Marines who arrived with the First Fleet in 1788.”

    While claiming our records go back 40,000 years it is too bad the BOM does not include any of the records before 1909. That might show there has been no warming at all.

    You mean unreliable reports like this?
    December 27, 1790: “Great heat in Sydney, 39C in the shade. Settlement visited by myriads of flying foxes, birds dropped dead from the trees.”
    February 10 and 11, 1791: “On which days the temperature at Sydney stood in the shade at 41C, the heat was so excessive at Parramatta, made worse by the bushfires, that immense numbers of the large fox-bats were seen to drop from the trees into the water, and many dropped dead on the wing.”
    There were hot days recorded in Sydney, and elsewhere, by Sir John Henniker Heaton in his 1879 Australian Dictionary of Dates. Here is a sample
    1826, November 29, in Sydney: 40C in the shade
    1832, March 18 in Sydney: 54C in the sun
    1833, February, in Bathurst: 41C (sun)
    1835, January 31, in Sydney: 43C (shade)
    1837, February 23 in Sydney: 56C (sun)
    1839, January 29, in Yass: 49C (sun)

      The MSM appears to be desperate to look the “victims” so they can shake off a lot of the criticism thats been rightly levelled at them.

    Harrabin’s chooses to get quotes from Neera Tanden,
    president and chief executive officer of the John Podesta-founded Center for American Progress and Andrew Light from the Obama Deep State Dept, who was Senior Fellow and Director of International Climate Policy at the Center for American Progress!

    24 Oct: BCC: Paris Agreement: Trump confirms US will leave climate accord
    By Roger Harrabin
    The US will definitely withdraw from the Paris climate agreement, President Trump has confirmed.
    He made the announcement at an energy conference in Pittsburgh on a stage flanked by men in hard hats.
    He described the accord as a bad deal and said his pro fossil fuel policies had made the US an energy superpower.
    The earliest he can formally start the process of withdrawing the US from the Paris accord is 4 November.
    The pull-out will take effect a year later – the day after the 2020 US presidential election – assuming that Mr Trump is re-elected.

    In the meantime, the president’s staff have conducted what critics call a seek-and-destroy mission through US environmental legislation.
    Mr Trump promised that he’d turn the US into an energy superpower, and he’s attempting to sweep away a raft of pollution legislation to reduce the cost of producing gas, oil and coal…
    The gas and oil industries are indeed thriving, but Mr Trump’s pledge to resurrect the coal industry has proved much more challenging.

    Coal can’t compete on price with gas – or, for that matter, with renewables whose costs have plummeted.
    Firms are also reluctant to invest billions in coal-fired plants which could have a limited life if the ***next administration rejoins the rest of the world on climate change…

    China – the current top emitter – and India still have relatively low per capita emissions, but Mr Trump said they shouldn’t be allowed to phase out fossil fuels more slowly than the US.
    He said: “The Paris accord would have been shutting down American producers with excessive regulatory restrictions like you would not believe, while allowing foreign producers to pollute with impunity.
    “What we won’t do is punish the American people while enriching foreign polluters,” he said, adding: “I’m proud to say it – it’s called America First.”

    Neera Tanden, from the liberal think tank Center for American Progress, said: “Instead of projecting strength, this action weakens America on the world stage and cedes leadership on climate change and other challenges of our time to countries like Russia and China.”…

    In fact, Chinese leadership on the issue has been muted recently as politicians there focus on avoiding a recession…
    The Beijing government is having difficulty persuading provincial leaders to abandon coal plants for which they have taken heavy loans.
    It’s also committed to a massive airport-building programme to stimulate economic growth. Critics say this is incompatible with concern for the climate…

    Andrew Light, a former State Department official during the Obama administration that helped broker the Paris agreement, said the formal withdrawal would make it difficult for the US to be part of the global conversation.
    “It will take some time to recover from this train wreck of US diplomacy,” he said.

        By the way albedo is about brightness and how much light is reflected
        Look at the Google Earth satellite photo link
        The albedo of the natural ground and the BOM station cleared & levelled area is quite different
        The BOM station is brighter.Light is being reflected somewhat
        But the energy of light is also being absorbed far more
        Generating more heat above that ground.

        Bill thanks for confirming my point. Excellent web link illustrating the sistuation. The met station area is brighter !

        Albedo is albedo. Put a black disk on the ground and a white disk. Measure temperatures and report back. Even AndyG could manage this.

        Zoom out a bit on your map and even darker areas appear in the landscape. So what is the “average” Giles area landscape that we wish to measure? Sampling problem?

        But agree let’s move Giles weather station to a more “representative” landscape area so it can read even hotter.

      The screen is set up on metal over deep red soil with gravel and bitumen nearby. The green-grey stuff in the blurry sat image is actually rather pale grass, if you cross check with Ken’s images expanded. I don’t know if that’s “talking science” or just common sense.

      I call it local heat contamination, as opposed to UHI contamination. The Watts team found that LHC was pervasive. The primary reason is economic development. Just one of several reasons why these regional and global surface warming statistics are pure junk. The satellites show no such warming.

          Peter Fitzroy

          Well, apart from precision and accuracy, the point I’m attempting to make is this, you are measuring a point, the temperature outside the screen will be different anyway, as is the road (and Vishy is right in his description), as is the rocks as is the temp a metre higher, etc etc. So it does not matter that much if the site is not exactly best practice in terms of the guidelines. No point measurement can really be taken as covering any other temperature than the position it recorded it at. Interesting the meteye product seems to be closer to the experienced temperatures especially on the coast (but then I live on the coast, and so that’s the information I need)

                Every temperature, at every site, good or badly situated is only measuring the temp of a very small space. Thus all temperatures for both weather, and climate are homogenised. For example, Newcastle covers both Wallsend and Merriweather beach – is the temperature the same in all 3 locations? No, so even weather reports are homogenised.

                I know you will not accept this, but perhaps the more clear header ones will.

        Fitzroy,

        You claimed: “Yeah, I saw that as well” after El Gordo’s; “Giles seems to show no temperature increase after the tar road went in, just saying”.

        Rather naïve of you Fitz! January is the typically hottest month at Giles and the radiative effect of bitumen located only 10m away is important including in calm weather. (Radiation is omnidirectional …. of equal intensity in ALL directions).
        Additionally, especially if there is a hot northwest or nor-nor-west wind, the advective heat transfer from the large effective cross-flow area over the bitumen would be serious.

        What is your wisdom concerning the January data in ACORN-SAT version 2 (degrees C)?

        1979 = 40.2
        1984 = 32.3 (month average down 7.9 from 1979)
        2011 = 40.1
        2012 = 34.6 (a difference in the month average of 5.5 in one-year)
        2013 = 40.1
        2019 = 40.5

        How did you draw that conclusion? From some other data?

      EG Please do not put the cart before the horse !

      Ken has checked out over 600 BOM weather stations so far.
      He has only checked them to see if they are compliant with the BOM’s own ‘siting’ guidelines.
      The BOM developed and adopted these guidelines as a scientific was of ensuring accuracy.
      But in these 175+ has NOT implemented it’s own guidelines.

      Ken has not checked the actual temperature record on those stations
      Neither have I recently.
      Though I spent a lot of time puzzling over the MT barker temperature record last December.

      But given how non compliant these BOM stations are,
      Checking out the temperature record of each of the 175 + stations, is beside the point.
      It would be a waste of time & effort.
      Why ?
      Because whatever data they provide is not reliable or accurate.

      Apart from the road encroachment, this site is pretty much unaffected by Urban heating effects from 1956 – 2019. Very little missing data.

      The trend in maximum temps is only 0.09ºC/decade up to when that road was put in…

      HUGE trend.. not

      When data after that road was put in is included, the trend becomes 0.14C/decade.

      So yes, that road may have made a slight difference to maximum temperatures.

        The 1956-2019 trend in minimum temperatures is 0.065ºC/decade

        And may have actually cooled since the road was put in.

      be cooler – the hot bitumen causes convection drawing in air from the cooler brighter surrounds. It’s a small strip in a much brighter general area. The station is not sitting on top of the road. That would be a major issue.

        Station is, however sitting on top of, and surrounded by, an area cleared of tussocky grass and shrub that is the natural vegetation of the area.

                the heat absorbing properties of a landscape does not depend just on albedo. The white sand example is a case in point. The silica rich sand heats up from the air around it and has a high heat capacity.

                Tussocky grass covered land is cooler because the grass has very poor heat absorbing properties. Vegetation remains cooler than just about any soil type (and I don’t see a field of pumice here)

                Vishnu, further to this is thermal mass which is independent of albedo. A bush has virtually none so that it matches changes in the ambient temperature almost immediately. Bare earth transfers (effectively stores) heat to a depth and will radiate that heat long after the air above it cools thus increasing the temperature of that air.

      Here’s the thing: any variation in mean max/mean min over a few decades is without much importance. The only thing at issue here is the alteration to the site which reduces “without much importance” to “of no use”. The comparison point is now corrupted, one starts again from 2011. By 3011 you might find an interesting trend or two, of slight importance. That’s if lengthy malfunctions or new alterations don’t corrupt readings. (Hint: they probably will.)

      Of course, this is not how the climatariat thinks!

      You can only know a vague amount about past climate from daily peaks and troughs. You can’t know how hot for how long, how hot if cloud had been present/absent at potential peak/trough time. Past min/max is a feeble statistic which can tell you a bit, and just a bit. (Precip records are more interesting, even though they don’t tell you nearly enough about how fast those gauges filled. And it only takes one guy hosing his Cessna on a dry day to give you a hundred-year flood.)

      Any modernisations are welcome…but no point running modern oranges against old apples, even if you squeeze and twist the apples to make them look more orangey.

      This gullible gobbling of flaky statistics really shames our age.

    “climate activist” – what is that?

    25 Oct: Natural History Museum: Greta Thunberg: New beetle named after climate activist
    Nelloptodes gretae bears little resemblance to its namesake – it is less than 1mm long, and has no wings or eyes.
    The insect does, however, have two long pigtail-like antennae.
    Scientist Dr Michael Darby said he chose the name because he was “immensely impressed” by the Swedish teenager’s environmental campaigning…
    By naming the beetle after Ms Thunberg, he said, he “wanted to acknowledge her outstanding contribution in raising awareness of environmental issues”…

    Sometimes animals are named after celebrities the scientists admire, as with the N. gretae beetle, or a spider called Spintharus leonardodicaprioi.

    And just last year, Donald Trump had another animal named after him – an amphibian that buries its head in the sand. The Dermophis donaldtrumpi was so named because of the US president’s comments about climate change…
    https://www.nhm.ac.uk/discover/news/2019/october/new-species-named-after-climate-activist-greta-thunberg.html

    has been picked up by all FakeNewsMSM, including the Trump reference in those I’ve checked:

    In fact he started with my local one here at Mt Barker SA.
    Ken is in Qld and here I am in SA.
    So we have never met nor even spoken on the phone.
    But it has been great reading his posts & adding my comments
    Over the past 4 months.
    It has become a real citizen science collaboration
    Such as I have never done . before.

    Before this I knew that something had gone wrong with the BOM
    But I did not know what.
    This project over the past 4 months
    Has truly opened my eyes.
    I had no idea that the BOM was so incompetent
    At gathering accurate basic observations.
    Before I has dome faith in the BOM’s professional expert capacity.
    Frankly now I have none.

    And all the Australian evidence of global warming
    Was gathered by BOM
    In this shoddy incompetent way.

    Who would have believed it ?
    And that is the message which needs spreading to the entire
    Australian people.

    The location of this and other weather stations is so bad that it has to go beyond incompetence and be a deliberate attempt to cause a warming bias in the collected temperature measurements.

    Jo, regarding “bitumen… runs within 10m of the Stevenson screen” near the beginning of your post, maybe you meant within 30m? Satellite views at google and bing suggest around 20m separation between Stevenson screen and bitumen, as does the BoM’s diagram.

    Other commenters noticed what appears to be an unpainted steel(?) base, which hardly seems a suitable choice for directly underneath a thermometer enclosure in a sunny locale. I live near latitude 51N… twice as far from the equator… and even here steel sitting outdoors in direct sunlight during summer is uncomfortably hot to handle (hands-on experience!).

          Peter Fitzroy

          no Robert – you are taking a point measurement, it can not represent anything but that particular spot. No site good or bad can be said to be representative of the area around it. I gave the example of Newcastle, which includes Wallsend (inland) and Merriweather Beach (on the coast).

          Even if you were standing next to the screen, the temperature you would experience, is not the temperature measured inside the box.

          Vishnu makes the point that apart from sitting, other factors will affect the measurement. For example the height above MSL is a big factor, a problem for the lower troposphere measurements done by UAH, as lots of them would be underground.

          So all measurements can only be considered as proxies for what is really going on.

          As the Giles site shows, the addition of a road has a ‘cooling effect’ on the site. Interestingly the mins are not as clearcut.

              Bill – the failure of the sites to meet the BOM guidelines is not the issue now is it. These are guidelines, they are not laws.

              What seems to be the thrust is that is the site does not meet the guidelines it should be ignored.

              However, say for the Sydney Observatory site, it provides a meaningful value for the temps in the City of Sydney, so although it is not compliant, it does have a use. Now that site is ignored when doing the ACORN dataset, as are most of the non-compliant sites.

              The second point is that somehow this poor site location effects temps by artificially raising them. Again this is what you experience so it is weather, and the site gives a good enough guide for the day to day.

              As I said earlier, the ACORN set which is for climate, excludes the worst of the non-compliant sites.

              So to answer your last bit – Exactly what cleaning up would you suggest, do you have a list of compliant locations to move the stations? If so you have never ever listed them. So stop complaining at provide something positive for a change

              /don’t be Andy

                The answer is simple it’s either yes or no and there’s no grey area here , what’s the point of putting the screens in if it doesn’t matter about the surrounds of the screen ? Might as well use a random number generator to work the temps out .

                Looking at a sat image of the site, where should it be?
                Looking at the data for the site, can you prove that it is not reasonably recording the temp etc?
                looking at the site, and given that it is only measuring a point temperature, what is the real temperature for that region?
                Looking at the data, could we conclude that it is reasonable guide to the weather experienced in that area?

                Instead of hunting for the mythical perfect (which for any number of reasons may not exist in that region) accept that this is good enough

    I have found it, not on the BOM site but a fishing site! https://www.fishranger.com.au/the_truth_about_weather_sites

    “In Australia there are currently 870 weather stations throughout the country. These stations are fitted with instruments that enable them to measure wind, rain, temperature and humidity. They are managed by the Bureau of Meteorology (BoM) and provide a network of current conditions around the country.

    Some stations record all weather variables while others record only some. Similarly, some stations record values every 10 minutes while others 30 minutes and some only once or twice a day.”

    So 7.7million km2 /870 = 8,505 km2 per weather station. That’s a box 94km x 94km. Or 200km between weather stations, evenly spread across the country. Of course perhaps half will be where people live or on the coast rather than the desert, so perhaps 200km between weather stations.

    And the 200km between stations is of constant temperature or changes linearly? Of course not. It would be interesting to see if a surface fitted to these points was smooth at all, or 870 quite different regions.

    So we know the temperature of the continent at all points to 0.001C? No. But there is nothing which cannot be homogenized, idealized, averaged to create whatever data you want. If you believe the surface temperature is not chaotic but smoothly varying. Well behaved, as it should be for the models to work.

    40

    • #
      TdeF

      I have ever been puzzled that these stations are say 1.4 metres about the ground. So we are measuring what people care about, the air they breathe.

      But the temperature there is not that at the ground or that for each 100 metres up, the air is roughly 1C cooler. And in a turbulent state, this is a 3D problem, not a 2D problem.

      Surely then we have the complexity of wind patterns over top of the temperature distribution. Everything from heat rising off a hot desert, an oasis to a willy willy or a full Lake Eyre or Channel Country or Monsoon rains can make nonsense of temperature. I suppose it can all be homogenized as we have to pretend it is smooth. Just so the IPCC can come up with their magic numbers. To 0.001C accuracy.

      Tell ‘em they’re dreamin’.

        Local temperature measurements are basically very rough indications of how much wind, rain and cloud there has been in the area.
        These three influences are overlaid on the 24 hour Solar input which is the only stable factor.

        There’s nothing “scientific” about weather records which are very roughly indicative of the local situation from month to month.

        As the Political arm of the Elites, known as the BOM, is obviously unaware of the fact that it is a scientific laughing stock maybe someone should do the right thing and shut it down.

          My comment was not about the height, but the fact that we are looking to predict the temperature of a tiny layer of air 1.4 metres about the ground, not to the many kilometers of air above it. Nor even the ground itself, which is often quite different just 1.4 metres below. People are so flippant about temperature but when you consider an atmosphere 20km thick and oceans 3.4km deep, this is a tiny area of interest in a gigantic 3D system. And therefore unpredictable.

          Arctic sea ice extent is still in the top 5% or so of the last 10,000 years and has a zero trend for the last dozen or so years.

            Sea levels have fallen a minimum of 4 metres in the last 7,000 years in an oscillating pattern that in some parts of the globe may have been 6 metres above present.

            This, of course, is reflected in more ice added to the poles.

            Oceans have fallen 1.2 metres in the last 2,000 years.

    The penny is finally dropping. Grid inertia is a problem for renewables.
    General Electric will demolish the 750 MW Inland Empire Energy Center (IEEC) in California that has 20 years remaining in its useful life. With solar and wind dominating the grid, the plant has been deemed uneconomical after operating well below capacity for several years. The site will be used for a new battery storage facility.

    Good news in terms of a zero-carbon future, right? Maybe not. A rush to retire such units may impair the ability of the grid to accept more solar and wind resources in the future. Why? It’s all about a factor known as grid inertia.

    A power network without inertia is one that is unstable, suffers from issues of power quality and is susceptible to blackouts. The primary mechanism for providing inertia is via the presence of heavy rotating equipment such as steam turbines and gas turbines driving generators and rotating generators.

    Efforts to decommission such equipment and replace them with renewable resources, while well intended, could inadvertently hamper the creation of the robust and reliable renewable grid of the future. Additionally, failure to invest in aging turbomachinery in an effort to achieve environmental targets could backfire. Operators could be forced to continue to operate dirty generating resources to provide grid stability and inertia when a small upgrade could greatly reduce emissions and improve the overall resilience of a renewable-focused power network.

      True CO2 emissions free power is only possible at this time with nuclear. Renewables require fossil fuelled power generators for backup. So the anti-CO2 cult is just that, a cult and a very dishonest, dangerous and ignorant one.

        PeterS:

        The other problem is that nuclear works best when running at a steady state, as it usually does because the output is then cheap (almost as cheap as brown coal fired). Yes, nuclear can be designed for variable output (load following) as in France where a third of nuclear stations merely have the steam bypass the turbines and go direct to the cooling towers. Output from other stations is directed into Germany, Switzerland, Italy and Spain (and through them to Portugal) by dropping the price.
        Alternatively the excess output can directed to pumped storage in the hydro scheme as happens in Switzerland (and Czechia) and used to happen in Sweden until ultra cheap excess wind generation was dumped on them by the desperate German grid managers. With enough low (even negative) prices for excess wind the Norwegians just shut down their hydro generators. And when the wind doesn’t blow hard enough do the Norwegians sell their hydro back at very low prices? HINT look up the origin of the word Viking.
        The Canadian CANDU nuclear can load follow somewhat, but is more expensive to run (i.e. cheaper than wind as people in Ontario found when the introduction of lots of wind turbines forced up their electricity bills.
        Newer nuclear processes being developed may be better, but it is unlikely that they can adjust to the variable nature of renewables.

    26 Oct: ABC: Hail survives two weeks of heat buried on outback Queensland property
    By Lily Nothling
    More than a fortnight since a hailstorm swept through central Queensland, a farmer was surprised to discover the ice on parts of his property had still not melted.
    Cattle producer Jack Walker found hailstones buried under dirt and debris on the outskirts of his farm near Theodore after the storm on October 11…

    “We were just thinking ‘wow’ — I haven’t got an esky that good that I can put ice in and keep it for two weeks.”…
    Since then, the region has experienced hot and sunny weather, with temperatures reaching close to 40 degrees Celsius.
    “It doesn’t seem to matter if it’s in full sun or partially shaded, there’s still hail there,” Mr Walker said.

    Bureau of Meteorology forecaster Dean Narramore said the slow-melting ice was an unusual phenomenon.
    “It’s a pretty impressive event — it’s pretty rare but it does happen occasionally,” he said.
    He said it occurred when large volumes of hail accumulated on creek or riverbanks, allowing the ice to “clump together” and mix with other debris.
    “The debris protects it from the heat and amazingly it almost acts like a fridge or freezer where you close the door and it keeps the cold in,” Mr Narramore said.
    “It can take quite a few weeks — which is amazing in the 40C heat — to slowly melt out.”…

    The farmer said he was finding novel ways to make the most of the long-lasting hailstones.
    “I actually put a pretty flash bottle of champagne there, but my wife said we’re not allowed to drink that until we get decent rain to celebrate properly,” he said.

    Last year I made an analysis of temperature trends at Giles and presumed that the records would be of high quality. This was because the station was manned by BOM observers and because it was far from other urban centres. Also the station had not been relocated since its commencement in 1956. https://briangunterblog.wordpress.com/2018/12/05/giles-maximum-minimum-temperatures/

    There are no obvious changes in the temperature trends in 2011/2012 when the road was sealed.

    Can anybody please tell me of any long-term (>100 years) met station in Australia where the data can be considered to be of acceptable quality? Ken Stewart has impressively identified stations which fail this test, but what about long-term stations that are okay?

    I don’t know why everyone is so upset about this blacktop road.

    The IPCC has assured us that convective heat transfer from the surface to the air does not exist. That well-documented phenomenon burning your feet is just your imagination. The IPCC authors are quite clear about this: the contribution of heat energy to the atmosphere above the temperature of the Earth without any atmosphere, currently a difference of 33 degrees Celsius, is solely the result of radiative processes involving Greenhouse gases. That’s right. The suggestion that blacktop roads cause any heating of the atmosphere is anathema. It is all due to GHG’s like water vapour and CO2 and that methy stuff.

    Have a look at their reports. Check with mullahs at RealClimate. “All warming above 255K is caused by GHG’s and associated radiative feedbacks.” There is no room for convective heat transfer from the surface to the air in that 33 degrees.

    If, on the other hand, heat energy were to be transferred from the surface to the air, they would have to consider that without GHG’s the air temperature would still be elevated above 255K because that value is taken from the surface of the moon, which has no atmosphere to get warmed. If heat transfer really did cool the 107 degree surface of an Earth with no GHG’s, then the air temperature would not be 255K, it would be some value higher. If it was higher, then GHG heating would not be responsible for the whole 33C, it would necessarily be some lesser value.

    Thus you can easily see that comparing the atmosphere we have now to a planet without no atmosphere at all is an inappropriate way to determine the respective magnitude of the convective heat transfer and the radiative feedback effects. If an atmosphere contained only non-radiative gases and was heated in the daytime by 1362 W/m2 it would get hot, and not cool until the loss of heat back to the surface at night equaled the large amount of heat gained by day. Given that a strong inversion layer would persist each night as the surface dropped to -150, the temperature at 1 km altitude would be far above today’s pleasant +15C.

    If you accept that blacktop roads somehow heat the thermometer inside that Stevenson Screen, you must also accept that without GHG’s the atmosphere would be a very warm place – the result of direct convective heat transfer of energy from the surface during the daytime. The fact that the IPCC ignores it in their explanation for the difference between the average surface temperature of the moon and the current near-ground temperature of the air, or that which prevailed in 1850, has no nullifying effect whatsoever on the thermodynamic facts of life, the universe and just about everything.
