Interferograms from Sentinel-1 were computed from both ascending and descending images acquired between 2016 and 2019. Since the French Alps are located in the Northern hemisphere, only the images acquired between June and October (i.e. in the summer periods) were used, in order to avoid the presence of snow cover, with an exception for a pair of images in February 2019 (with cold snow on most the high elevation terrain, allowing coherent InSAR signal).
