Abstract :
Radar altimeter data from ERS2 satellite have been processed across The Northern Great Plains of U.S for an entire snow season and compared to in-situ measurements. We show that cover strongly decreases the variability and the intensity of the backscattering coefficient. The decrease in backscatter can be related to snow depth
