Abstract
The distributed biosphere hydrological model (WEB-DHM) was physically improved in snow physics, by incorporating the 3-layer energy balance based snow module of the Simplified Simple Biosphere 3 (SSiB3) model and albedo module of the Biosphere Atmosphere Transfer Scheme (BATS). The new version of WEB-DHM is referred to as WEB-DHM-S. In this study, the WEB-DHM-S is evaluated at Valdai site (Russia) from 1966 to 1983, to check its performance in simulating the interannual variability of snow cover. Results show that the WEB-DHM-S is capable of reproducing the point-scale interannual variations of snow water equivalent, soil and snow surface temperature well. In addition, the good performance of WEB-DHM-S was further confirmed in simulating soil moisture (top 1 m) and evapotranspiration.
