Document Summary

The balance between solar energy coming into the earth, the energy absorbed by earth and then earth omitting energy back out. Energy emitted by earth is much less than by the sun. Orange areas the energy is emitted through the atmosphere to the space = very little absorption. The long wave radiation emitted by earth absorbed by gases in the atmosphere and then re-emitted back to earth. As the gas concentration increase and longer wave radiation is emitted. No atmosphere at all will equal to -15 temperature. How insolation varies over globe: incoming solar radiation. Depends on the angel of the sun over the horizon. The lower the angel the higher surface area. Dramatic change of energy depending on the angle of sun over earth. The scatter is inversely proportional to the wavelength. The blue is intensely scattered over the solar beam. Short wavelength blue is scattered more than the longer wavelength (red).
