Glaciers in the European Alps are known to be strongly affected by global climate change. Here we provide temporally consistent changes in glacier area, surface elevation and ice mass over the entire European Alps between 2000 and 2014. Our measurements show strong glacier surface lowering throughout the European Alps with regional variability in average ice thickness changes (-0.5 to -0.9 ma-1). For the entire Alps we estimate a mass loss of 1.3±0.2 Gta-1 (2000-2014). Our results provide important information for future socio-economic research, such as water resource management, tourism and risk assessment, and for the calibration and validation of glacier change projections.
The dataset includes glacier elevation change maps (GeoTiffs) of the entire European Alps for the periods 2000-2012 and 2000-2014. Elevation changes are derived from differencing Digital Elevation Models (DEMs) of the SRTM and TanDEM-X satellite missions. Average surface elevation change rates (ma-1) were calculated based on specifically generated glacier outlines (2000, 2011 & 2014) and outlines of the Randolph Glacier Inventory (V6.0 Central Europe). Elevation change maps are cropped to Randolph Glacier Inventory outlines and the spatial union of specific glacier outlines from 2000 and 2011 (for elevation change 2000-2012) and 2000 and 2014 (for elevation change 2000-2014), respectively. See the associated publication for further details regarding the datasets and calculation of surface elevation change and geodetic mass change with a temporal mean area. All elevation change maps are provided as GeoTiffs with a spatial resolution of approximately 30m. Please note that the provided elevation change measurements are not filtered (no outlier removal applied).
The observation period of each raster cell is measured in years between the respective TanDEM-X DEM and the SRTM reference DEM. As reference date the mean date of the SRTM mission (2000-02-16) is used.
