A. Heating of the Atmosphere by Direct Insolation
◇ The heat energy is radiated from the outer surface of the sun (photosphere) in the form of long waves.
◇ The atmosphere absorbs 14 per cent of incoming short wave solar radiation through ozone, water vapour etc. present therein.
◇ Seven per cent of this energy is spread in the lower atmosphere up to the height of 2km. It is apparent that this amount is too low to heat the atmosphere significantly.
