SummarySnow and ice are key elements of the climate system, responding very sensitively to changes in temperature and precipitation, and interaction with other climate variables through complex feedback mechanisms. The main objective of this project is to map and to monitor the snow cover (wet snow, dry snow etc.) of the both glacier Gepatschferner and Vernagtferner in Tyrol, Austria, and of the Baltoro glacier in the Karakorum, Pakistan. The snow cover will be derived using the change detection.The chain detection contains four main steps: kennaugh decomposition, geocoding, radiometric enhancement and normalization. For that purpose, dual-polarized TerraSAR-X data are required. In order to have the same acquisition geometry, the data of the time series must be aquired of the same orbit. The results are compared with data of the meteorological stations which are fixed in both test sites. Addionally, the results of the kennaugh decomposition will be evaluated with ground truth campaigns.
