Quiz # 2 --> in class on Moday, October 18 Compute the net radiation assuming only one cloud in the atmosphere. The outgoing longwave radiation is done for you! You compute the net shortwave radiation from the formulat below: The cloud has cloud top temperature Ttop=250 K and albedo A=0.2 Recall that S=1370 W/m2 The outgoing longwave radiaion is Fout=(sigma)T4=221 W/m2 a) The net incoming shortwave radiation is Fin=(S/4)(1-A)= b) Fin-Fout= c) Will this cloud cause the atmosphere and surface to warm or cool?
