Classification of snow cover and precipitation using ssnii measurements: Case studies

This study uses three of the SSM/I channels to classify snow cover and precipitation on a global basis. The technique is based on the physical relationship between the antenna temperature measurements (Ta' s) at low and high frequencies and their response to scattering materials such as snow cover or precipitation. An advantage of this technique is that it uses only three SSM/I channels (85V,22V,19V) for classification, as opposed to a technique like principal component analysis which uses all 7 SSM/I channels.
