This study involves the identification of snow facies of Gangotri-Badrinath glaciated region using multi-temporal synthetic aperture radar (SAR) data for different frequencies sensors. For snow facies mapping the methodology is adopted involving co-registration of multi-temporal SAR data of different season winter, early summer, and late summer for C- and L-band. Further co-registered SAR images were used to generate false color composite (FCC) for mapping of different snow facies and zones of Gangotri-adrinath glaciated region. The SAR FCC is generated by assigning blue to winter, green to late summer and red to early summer. In the SAR FCC image dry snow facies appear as dark gray tone, percolation facies in white to purple tone, wet snow facies in blue tone and the ice facies in green tone. However the separation between percolation facies and wet snow facies is not distinct at both frequencies. Layover areas appear in bright white in both SAR FCC images.
