Document Summary
1372 w/m2 is the solar constant which is the amount of energy that hits the top of our atmosphere. Come through directly to earth direct radiation. Comes to the earth after bouncing around in clouds and off matter in the atmosphere diffuse radiation (scattering) Reflected to space reflection: direct/diffuse pathways do work creating energy. 3 shortwave radiation pathways: diffuse radiation has a longer path through out atmosphere and is sometimes called scattering, direct radiation is energy transferred directly from the sun to earth, reflection to space by the atmosphere. Longwave energy pathways (harder to define because there are more than 1 source). Surface captures energy, heats up and gives back some of the energy. The atmosphere than absorbs the longwave energy and returns some of it back to earth and directs some of it towards space. Transmission refers to the passage of shortwave and longwave energy through the atmosphere to water.
