Content
-------
This data supplement contains shapefiles (.shp, .cpg, .dbf, .prj, .shx) of CryoSat-2 Swath derived glacier surface elevation change rates and corresponding uncertainties between 2010 and 2019 for the two study areas:
- High Mountain Asia: hma_datasupplement.shp
- Gulf of Alaska: goa_datasupplement.shp
