Abstract

Snow Water Equivalent (SWE) in Western Siberia during 1979 to 2013 period was simulated using Land-Surface Model (LSM) SPONSOR forced with meteodata from the ECMWF ERA-Interim reanalysis. Fields of SWE with high spatial and temporal resolution were obtained. Maps of February average SWE were computed for satellite data, reanalysis and SPONSOR model simulations. A comparison between the SWE maps shows a significant uncertainty. It is shown, that none of the methods cannot be currently used as a reference for determining SWE when there is no data of ground-based observations. Simulations using LSM SPONSOR reasonably well reproduce SWE for Central, Eastern and, most probably, the Northern parts of the region.
