Insolation is the solar radiation that reaches the earth's surface. It is measured by the amount of solar energy received per square centimetre per minute.

Insolation affects temperature. The more the insolation, the higher the temperature.

In any given day, the strongest insolation is received at noon.

Factors affect insolation (without the effect of the atmosphere):

• Angle of the sun
• Distance between the sun and the earth
• Duration of daylight

The longer the duration of daylight, the more the insolation received.
