The data contained in Adjet_Rock_Glacier_Data.zip are a part of a manuscript entitled “Recent Acceleration of a Rock Glacier Complex, Ádjet, Norway, Documented by 62 Years of Remote Sensing Observations” by Harald Øverli Eriksen, Line Rouyet, Tom Rune Lauknes, Ivar Berthling, Ketil Isaksen, Heidi Hindberg, Yngvar Larsen and Geoffrey D. Corner, submitted to the journal Geophysical Research Letters. Adjet_Rock_Glacier_Data.zip includes several zip-files: ArcGIS.zip contains an ESRI ArcMAP project, shapefiles of contour lines, and raster images of a DEM and two orthophotos covering the study area. Area_Used_for_Comparison.zip containing a shapefile of area used for comparison of mean yearly velocity from offset-tracking data, TRI data and orthophoto comparison. Climatic_Data.zip contains an excel with modelled gridded climatic data (daily air temperature, daily precipitation and snow depth). Data_Used_For_Comparison_Fig2a_and_b.zip contains shapefiles and raster images used as source for Figure 2a and b. Deformation_Data_extracted_from_Profile_AA_Fig2_Fig3.zip contains excel-sheets with deformation data extracted from profile A–A’:- 2D_Vectors_velocity_(length)_and_plunge_from_TSX_OT.csv containing 2D vector velocity and plunge of displacement from combined offset-tracking data from both TerraSAR-X ascending and descending geometries (2009–2014). Data are extracted using a 40 m buffer along profile A–A’.- Deformation_Data_Clipped_from_Profile_AA.xlsx contains projections and calculations of velocity, strain rate, subsidence and uplift data used in Fig. 2 and Fig. 3.- Extracted_Dem_and_Slope_Along_Profile_AA_10m_buffer.csv contains height and slope extracted from profile A–A’. Deformation_Reference_Area.zip includes the area used to reference InSAR and TRI displacement data. Displacement_From_Orthophotos.zip with shapefiles giving displacement made by comparing position of boulders identified in orthophotos (1954–1977, 1977–2006 and 2006–2014). Front_and_Scree_Apron_From_Orthophotos.zip with shapefiles of rock glacier fronts (1954, 1977, 2006, and 2014) and out limit of scree aprons (2006 and 2014) interpreted from orthophotos. Instrumentation.zip contains shapefiles with position of in-situ instrumentation. Profile_Line_AA.zip contains shapefile giving the extent of profile line A–A’. Surface_Deformation_From_Glens_Flow_Law.zip containing an Excel-sheet with calculation of surface creep using Glen’s flow law. Terrestrial_Radar_Interferometry.zip with raster datasets of accumulated displacement (TRI_deformation), calculated mean yearly displacement based on campaigns (TRI_mean_yearly_vel), and mean coherence for the 2014 and 2015 campaigns. TSX_InSAR_Desc_Orbit.zip with a raster dataset based on 75 TerraSAR-X StripMap snow-free SAR scenes from descending geometry. TSX_OT_Descending_Orbit_Proj_Into_Horiz_Plan_(m_per_year).zip with raster datasets giving the displacement of the rock glacier projected into the horizontal plane using offset-tracking data from TerraSAR-X scenes acquired in descending orbit. Based on scenes from the snow free seasons mean yearly displacements in meters are given (Offs_total_vector_lenght) for the years 2009, 2010, 2011, 2012, 2013, 2014 and 2016, and the total timespan 2009–2016. Datasets for the azimuth direction in degrees (Offs_tot_azimuth), north component (Offs_north) and west-east component (Offs_horiz), both in meter per year, of the displacement are also included.
