INSOLATION AND HEAT BUDGET#

 INSOLATION:

The incoming solar radiation or the energy that the earth receives from the sun is known as Insolation.

  •  Only approximately 52 per cent of this insolation reaches the earth's surface. 
  • The rest is absorbed by water vapour , dust and clouds, or is reflected by the Earth's surface and scattered by particles in the air.
HEAT BUDGET:

  • A heat budget is a perfect balance between incoming heat (insolation) absorbed by the earth and outgoing heat (terrestrial radiation) escaping it in the form of radiation. 
  • If the incoming heat and the outgoing heat are not balanced, then Earth would be getting either too warmer or cooler.
  •  Since these are perfectly balanced the earth is neither too warm nor too cold.
That's it for the day,
THANK YOU..,
