Document Summary
Insolation at earth"s surface: at certain points on earth albedo is high because of certain altitudes, as you start to move away from the equator it is less, the red has the most, 1. Reflections: a portion of insolation bounces back into space without being absorbed reflections, the reflective quality of a surface albedo. If you have more dust and gases into atmosphere, the sun is not going to pass through the atmosphere so reflected back to space: (2. , (3. ) Absorption: the assimilation of radiation by molecules of matter and its conversion from one form of energy to another = absorption, any insolation that isn"t part of the 31% reflected from earth"s atmosphere and surface is absorbed. It varies with latitude and season (also, no surprise: more of a surprise lag time = time of maximum radiation is not time of maximum temperature, takes time for the energy to reach the surface of the earth.
