11.12.17 Master in Environmental Geoscience (MSc GSE) Estimation of snow cover patterns in the Swiss Alps by remote sensing Contact persons: Gregoire Mariethoz, Mathieu Gravey Context Snow cover extent and duration are key environmental variables in alpine environments. They control processes such as the hydrology of alpine catchments and the distribution and diversity of plant species. However, obtaining maps of snow is very difficult. In-situ data are difficult to acquire in inaccessible areas. Remote sensing observations offer a promising alternative, especially because snow is relatively easy to detect on some multispectral satellite products. However, it is difficult to obtain long time series of snow cover and duration because satellite images are very infrequent before about 2013. This project aims at generating such long time series by using the frequent observations made by different satellites launched after 2013, and propagating these observations in the past based on climatic observations that are available since 1981.
