Abstract

Scientific research using advanced observation technologies and mathematical models aimed at estimating seasonal snow cover and its water equivalent (SWE) helps to reduce the costs of snow cover monitoring and improve the management of the soil-water-crop system. Following the above goals, this paper analyzes two approaches - the Community Land Model (CLM) producing own calculated data, and the ESA GlobSnow v.3.0 product based on the European Space Agency (ESA) GlobSnow project satellite data. The studies were carried out in the period 2016-2020 for the Sought Central Region of Bulgaria. The results indicate a significant reduction of snow. The SWE results of the CLM model (covering the whole study area) are compatible with the SWE data produced by the GlobSnow product, which is easy for use, but applicable only for non-mountainous areas.
