Active rock glaciers are slow-moving, permafrost landforms that characterize high mountain periglacial terrains. Their complex movement, with interannual and subseasonal rhythms, are of interest for interpreting the evolution of the permafrost in response to meteorological and climatic variables. Given the generally remote location of the rock glaciers, we propose a methodology to monitor their interannual and subseasonal dynamics using a satellite-based approach with different types of Synthetic Aperture Radar (SAR) imagery (i.e. Sentinel 1 and TerraSAR-X), limiting the need of in-situ measurements. This proposed methodology is tested on an active rock glacier, where many in-situ measurements are available to compare the satellite results.
