Glacier boundaries (1975-2020) and elevation change (2000-2020) of the Peruvian Cordilleras Vilcanota, Vilcabamba, and Urubamba

This dataset contains glacier boundaries from 1975 to 2020 and elevation change data from 2000 to 2020 over the Cordilleras Vilcanota, Vilcabamba, and Urubamba, Peru. Glacier boundary data were analysed in Google Earth Engine from the Landsat archive and quantifies rate of change in ice extent over recent decades. Elevation change data were analysed in Google Earth Engine from the ASTER archive and quantifies change in ice thickness over decadal intervals from 2000 to 2020. Data are available as shapefiles (.shp) and GeoTIFFs (.tif). Summary data are available as CSVs (.csv).

This work was funded by NERC SPHERES Doctoral Training Partnership (NE/L002574/1) and NERC Newton Fund (PEGASUS) (NE/S013318/1).

Statement
All 1984 - 2020 glacier boundaries have an accuracy of 5%, with the 1975 Landsat-2 scenes at 11% owing to larger pixel sizes in the original dataset Volume change error is calculated as a median of off-ice areas within a 2 km buffer of glaciers and this error carried forward to calculate mass (following Brun et al. 2017) and mass balance.
