Abstract :
Microwave data (TOVS) from NOAA satellites are used to monitor snow coverage in this study. The spectral difference between MSU-1 (centered at 50.31 GHz) and HIRS/2-8 (Centered at 11.10 μm) is used to identify the cloud free area; the MSU-1. HIRS/2-8 and HIRS/2-19 (centered at 3.70 μm) are combined to screen out the non-snow target with high albedo; finally the reflection character of HIRS/2-20 (centered at 0.70 μm) is used to distinguish snow. Two tests were made to compare with the real cases of snow coverage in the east of China in January, 1993, and the east of the Tibetan plateau in 1991
