Description
We used Sentinel-1 Synthetic Aperture Radar Interferometry (InSAR) to measure the ground surface displacements in the permafrost landscape of Svalbard. The InSAR products document thaw subsidence and frost heave related to the seasonal active layer thawing and freezing in 2017. The displacement time series were used to extract the timing of the seasonal thaw subsidence maxima at the regional scale.
We analysed three study areas in central and western Spitsbergen (78–79°N, 11–16°E): Adventdalen (ADV), Kapp Linné (KAP) and Ny-Ålesund (NYA). The dataset consists of one .csv file for each study area, which includes June–November 2017 InSAR displacement time series, the identified subsidence maxima and their corresponding Day of Year (DOY) for all the documented pixels. Details about processing and file attributes are described in the Readme pdf document included in the dataset folder.
