Data created by Chunli Dai et al. (chunlidai@ufl.edu).

Format: ESRI Shapefile (Polygons)
Projection: EPSG:4326 (Lat/Lon WGS84)

ArcticRTS.shp: Digitized polygons of retrogressive thaw slumps.
Data format: Bounding box of the polygon, longitude, latitude, total area of each RTS (m^2, 'SHAPE_Area'), zone type, latitude and longitude of the center of the polygon ('lat','lon'), region id names (ArcticDEM convention,'regionid'), total volume of each RTS (m^3, 'volume'), total volume uncertainty (m^3, 'vol_std'), median volume loss per year (m^3/year, 'med_vpy'), the uncertainty of median volume loss per year (m^3/year, 'med_vpystd'), mean elevation decrease over the scar area (m, 'dh_ave'), peak elevation decrease (m, 'dh_peak'), ftp link to corresponding file names for elevation change maps ('file').

VolLatlon.shp: Shapefile that contains the correlation data and other information.
Data format: longitude, latitude, total volume of each RTS (m^3, 'volume'), median volume loss per year of each RTS (m^3/year, 'med_volperyr'), the correlation of volume loss per year with the temperature (July August, 'cor_T'), the correlation of volume loss per year with the precipitation (July August, 'cor_P07'), the correlation of volume loss per year with the precipitation (April May June, 'cor_P04'), volume loss acceleration (m^3/year^2, 'vol_acc'), uncertainty of volume loss acceleration (m^3/year^2,'vol_acc_std')


RTSTIF: the 2D elevation change map product for each RTS in ArcticRTS.shp
Naming convention: slumpID_filetype, where ID is the slump id (e.g., 682), filetype is (jump.tif).

30_45_1_1_11_25_listused.txt: a list of ArcticDEM strip file names used for change estimation.
slump1_jump.tif: elevation change in meters.
slump1_jumpstd.tif: elevation change uncertainty in meters.
slump1_eventtimeT1.tif: date of the closest measurement before detected change. The date format is YYYYMMDD.
slump1_eventtimeT2.tif: date of the closest measurement after change. The date format is YYYYMMDD.
slump1_nov.tif: The number of overlapping DEMs used for each pixel. Unit-less.
slump1_bitmask.tif: Integer flag of whether the estimated change has a high confidence level. 1 is high confidence, and 0 is bad/low confidence. Unit-less.
slump1_curvature.tif: DEM curvature unit-less.

One slump may include multiple *listused.txt files, since one area may cover multiple sub-tiles.

They are Geotiff files, which can be visualized in QGIS (open software). You can also read the files using Matlab code (https://github.com/ihowat/setsm_postprocessing/blob/master/readGeotiff.m).

Geotiff files are in Arctic Polar Stereographic projection (EPSG:3413).
The ArcticDEM naming convention (e.g., arcticdem_31_alaska_south): Data product acronym such as ArcticDEM, following that, it's the region id (31) and short region names (e.g., alaska_south).
