Dataset documenting ground movement and environmental conditions at 68'590 common pixels (40 m resolution). Study area: ca. 148 sqkm area in the Gaissane mountain massif, County of Troms og Finnmark, Northern Norway (70°00'N, 26°14'E). Ground movement associated with cryoturbation and solifluction has been detected using a distributed scatterers Synthetic Aperture Radar Interferometry (InSAR) technique based on Sentinel-1 satellite images (2015-2018). Two-dimensional information (vertical and horizontal in the East-West plane) has been retrieved by combining InSAR results from ascending and descending SAR geometries. The results are expressed as mean annual ground velocities (mm/yr). Seven environmental variables are documenting the climatic, geomorphic, hydrological and ecological conditions at similar locations. The dataset was used to perform statistical modelling using generalized linear model, generalized additive model, generalized boosting method and random forest. : In relation with a manuscript submitted in JGR: Earth Surface "Environmental Controls of InSAR-based Periglacial Ground Movement in a Sub-Arctic Landscape" Funding: Research Council of Norway (grant 263005) and Academy of Finland (grant 315519)
