1. The problem statement, all variables and given/known data Consider a snow-covered surface. Assume that the amount of solar radiation that reaches the top of the atmosphere is 1367 Wm-2. Given that 50% of this solar radiation is either absorbed in the atmosphere or reflected by clouds before reaching the the snow covered surface, how much of the original shortwave radiation is absorbed by the snow? 2. Relevant equations Hr= (Area)(e)(5.67x10^-8 W/m^2K^4)(temperature)^4 3. The attempt at a solution I seriously dont know how to.. please help me..
