Remote Sensing of Snow and Ice Using Nimbus-7 SMMR Data over Finland
Nimbus-7 SMMR data at 18 GHz and 37 GHz are applied to studies of snow-covered sea ice and snow-covered terrain in Finland. First the dielectric properties of sea ice, snow, and frozen soils are reviewed. Brightness temperatures are calculated using the radiative transfer model. The theoretical resu...
