| Abstract: | SSM/I data over the desert areas of China
is studied. Temporal variations of the brightness
temperatures TB from SSM/I observations
are presented.The polari TB zation index of 37GHz channels is
defined as an identification index to
the desertdistribution.Its spatial and temporal variations
are discussed. The radiative transfer theory
is used to simulate the TB of desert area at SSM/I
channels,which includes the effect of atmospheric water vapor,surface roughness, and vegetation coverage etc. This analysis has developed an useful approach to the desert study in China. |
