insolation = incoming solar radiation

The atmosphere is an open energy system receiving energy from both the sun and the earth.

Incoming radiation from the sun is short wave, outgoing radiation is long wave.

The sun's energy drives all weather systems and climates. Most is absorbed in tropical latitudes and redistributed to polar latitudes.
