Homework Help: Thermal Radiation

  1. Sep 28, 2015 #1
    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..
