100% of the energy entering earthâs atmosphere comes from the sun. ~50% of the incoming energy is absorbed by the earthâs surface i.e. the land and oceans. ~30% is directly reflected back to space by clouds, the earthâs surface and different gases and particles in the atmosphere (the earth's albedo is 0.3 on average). ~20% is absorbed by the atmosphere and clouds. The 70% of the sunâs energy that is absorbed by the earthâs surface, clouds, and atmosphere causes warming. Any object or gas that has a temperature emits radiation outward, and this is ultimately re-radiated back into space.
The fraction of the total solar radiant energy reflected back to space from clouds, scattering and reflection from the Earthâs surface is called the albedo of the Earth-atmosphere system and is roughly 0.3 for the Earth as a whole.igure 2.1: The Sun's rays incident on the Earth. I0 = irradiance on a plane perpendicular to the Sun's rays. The solar constant (I SC) is the average radiation intensity falling on an imaginary surface, perpendicular to the Sunâs rays and at the edge of the Earthâs atmosphere (figure 2.1).
