Discrimination of Arctic multi-year ice from first-year ice using SCATSAT-1 data
The distinctive dielectric properties of multi-year ice that make it stand out from the first-year ice has been exploited in this study to discriminate the Arctic multi-year ice from the first-year ice. We have used the backscattering coefficient, the brightness temperature and the gamma-naught data...
