Are Insolation and Terrestrial Radiation the Same?

Insolation is measured by the amount of solar energy received per square centimetre per minute. Terrestrial radiation is measured using the Precision Infrared Radiometer. Insolation which is received on the earth's surface is not uniform . It is maximum in the tropical regions and minimum towards the poles.

What is the difference between insulation and radiation?

The energy emitted by the sun is known as solar radiation. The incoming solar radiation to the earth is known as insolation. ... Radiation from the earth is called terrestrial radiation.

What is the balance between insolation and terrestrial radiation called?

Heat Budget of the Earth

This can happen only if the amount of heat received in the form of insolation equals the amount lost by the earth through terrestrial radiation. This balance between the insolation and the terrestrial radiation is termed as the heat budget or heat balance of the earth.
