Question

What do you mean by insolation?

Answer 1

Insolation is defined as the amount of solar energy received by the Earth. It refers to the incoming solar radiation intercepted by the Earth, mostly in the form of short-wave rays from the Sun. Only a portion of the total solar energy emitted by the Sun reaches the Earth, as some is dissipated, scattered, or reflected back into space. Insolation is the primary source of energy that heats the Earth’s surface and atmosphere.
