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..,
