Brightness Temperature Over the Indian Subcontinent

Special Sensor Microwave/lmager (SSM/I onboard the Defence Meteorological Satellite measures brightness temperature. Microwave remote sensing sensors have the capabilities of sensing the Earth surface through cloud cover day and night. Using these sensors, day to day monitoring of Earth, ocean and snow covered regions can be effectively carried out. In the present paper, we have analysed the brightness temperature observed by the Special Sensor Microwave Imager (SSM/I) satellite over the Indian subcontinent. The brightness temperature over the lndian subcontinent shows characteristic fentures over snow, ocean, desert and land regions. The contrast in brightness temperature over ocean and land regions is seen which is plausible due to contrast in the dielectric properties of ocean and land.
