background image GY 101 WEEK 4 9/13 Radiation Balance and Thermal Properties of Surfaces  Reflected near Surface Reflected (albedo) reradiated as Shortwave (k ^) Absorbed reradiated as Longwave (L ^) Scattering (seeing colors) when you see color what you’re seeing is the wave lengths radiation, where 
all colors are being absorbed expect the one you see which is being reflected
Rayleigh scattering gives the atmosphere its blue color Absorption (pg. 57) red; radiation at sea level yellow; sunlight at top of the atmosphere black line; blackbody spectrum black absorbs all colors white reflects all colors               Radiation Balance Equation (do not need to memorize) energy neither created nor destroyed !
Q*= (K (down) - K (^)) + (L (down) - L (^))
Q* is net radiation K is a short wave (sun) L is a longwave (earth) if Q* is not 0, warming or cooling must occur The “Greenhouse” (pg. 63)
