The freeze/thaw cycle of the Earth´s surface determines the timing and the length of the vegetation growing season. Applications like permafrost monitoring and climate studies require information on the freeze/thaw state, however, conventional methods such as temperature records from in-situ stations are often severely hampered by the low density of weather stations. In order to obtain a global dataset of the freeze/thaw cycle, satellite remote sensing methods provide a good means since their observations of albedo, temperature or backscatter can be used to infer surface freeze/thaw state. The aim of this work was to derive freeze/thaw state from backscatter measurements by the scatterometer on-board the European Remote Sensing satellites. The results were validated against different soil models and in-situ networks.
