Kraaijenbrink, P. D.A., Bierkens, M.F.P., Lutz, A.F., & Immerzeel, W.W. (2017). Supplementary data: Impact of a global temperature rise of 1.5 degrees Celsius on Asia’s glaciers (Version 1.0) [Data set]. Zenodo.
The raster data that is required to run the model can be downloaded from the links below. There are separate links for the entire High Mountain Asia and for each RGI v5.0 sub-region. The downloadable 7z-archives hold separate folders for each glacier, which are named with the RGI glacier IDs. The rasters for each glacier are in GeoTIFF format, have a 30 m resolution in their local UTM projection (WGS84 datum), and are clipped to the RGI glacier extent.
