Question
State how the Global Heat Balance is achieved?
Solution
Out of 100 units of solar radiation 35 units are reflected back by atmospheric layers and clouds and snowfields etc, 14 units are absorbed by the ultra-violet rays in the ozone layer and only 51 units are received by the earth as insolation and again these 51 units are reflected back by terrestrial radiation out of which 34 units are absorbed by the earth and sent back to atmospheric layers and 17 units radiated back into space. This process is called the Heat budget or Global Heat Balance.
