Maximum energy is received at the equator and between 30 deg. N and 30 deg. Minimum energy is received at the poles above 66.6 deg. N and 66.6 deg. Transport of heat by ocean currents and atmospheric circulation.
Incoming radiation is shortwave, visible light.
The percentage of light reflected back into space is dependent on Earth's albedo . Light colored surfaces have high albedo and dark objects have a low albedo. The type of surfaces on Earth and the amount of clouds determine the Earth's albedo. Outgoing radiation besides reflected light is longwave radiation such as heat. As light warms up the land, air, and water some of this newly formed heat radiates back into space.
