Earth observation snow water equivalent
EOSWAN is a CDTI funded research project, in collaboration with the company Starlab, focused on the quantitative estimation of significant snow parameters, such as the snow cover map, snow density or the equivalent amount of water (SWE – Snow Water Equivalent), based on Earth observation data. Specifically, it focuses on the study of polarimetric C-band SAR data for the development of an inversion model for significant snow parameters. The novel nature of the project is on the quantitative estimation of snow parameters from C-band polarimetric SAR data from the Canadian sensor Radarsat-2 on the Catalonia Pyrenees.
