Abstract :
It has been proved successfully in Choudhury (1987, 1988 and 1989) that the microwave radiation of the Earth, as detected by the Scanning Multichannel Microwave Radiometer (SMMR) sensor on board of NIMBUS-7 is influenced by the structure of the vegetation. The present study explains that the difference of vertically and horizontally polarized brightness temperatures at 37 GHz frequency is directly related to the difference of polarized emissivity at 37 GHz and inversely related both to the atmospheric transmittivity and surface temperature
