A water cloud with a 2-km vertical thickness is characterized by a thermometric temperature profile of the form T(z)= 300(14 10-2) where z is the height in km above the base of the cloud. Calculate Tup and TDN for 03D60 and (a) K.=10-4 Npkm- (b) K=10-3 (c) K.=10-2 Np km . 1- %3D %3D Are Tup and Tpy the same? If not, why not? Tup is defined as the upwelling brightness temperature observed by a radiometer located above the atmosphere and looking down, and Tan is defined as the downwelling brightness temperature observed by a radiometer at the ground looking up.
