New developments and results for snowcover monitoring using RADARSAT and VEGETATION data and the HYDROTEL hydrological model

The HYDROTEL hydrological model was developed to be compatible as much as possible with remote sensing and GIS data. In parallel, processing procedures to derive snowcover characteristics from RADARSAT and VEGETATION data have been developed for updating purposes in the HYDROTEL model. In the case of RADARSAT data, we are now testing the possibility of using the French CROCUS snowmelt model to derive the snowcover information used in our RADARSAT algorithm. As for VEGETATION data, we have added corrections for bi-directional effects in the algorithm, using a procedure developed by the Canada Centre for Remote Sensing. We finally explain how we intend to use that information for updating the snowcover as simulated by HYDROTEL.
