fate of incoming solar radiation Flashcards
1
Q
what is scattered?
A
-small dust particles and gas molecules in the atmosphere scatter some of this energy in all directions
-diffused light - explains how light reaches
2
Q
what is reflection?
A
-light bounces back from an object at the same angle at which it encounters a surface and with the same intensity
3
Q
what is albedo?
A
fraction of total radiation that is reflected by a surface
4
Q
what is absorbtion?
A
-gases are selective absorbers
-N2 poor absorber
-O2 and O3 efficient absorbers of UV
-water vapor efficient absorber of infrared
-non of the atm. gases are effective absorbers of visible radiation
