Lapse Rate – There are two different types of lapse rates. The normal or environmental lapse rate is the rate that stationary air cools as a thermometer rises up through it (about 6.5 degrees C per Km). The adiabatic lapse rate refers to air that is itself rising up through the atmosphere. Because air expands as the pressure falls, even large “parcels” of air will cool as they rise. Rising dry air loses heat  faster (10 degrees per km) than rising humid air (6 degrees per km). [Enc Brittanica, UWSP]

    I think HADcrut as defined above is missing something. “CRU” portion refers to the University of East Anglia’s Climate Research Unit (CRU) which provides the land temperature portion of the combined temperature dataset – usually listed as “HadCRUT” and may be followed by a data set revision number (i.e. 1, 2 or 3).

    Glad your site is back up.
