For quick inspection I recommend ncview. Conversion to GeoTIFF (and other GIS formats) can be achieved with e.g. GDAL:: gdal_translate NETCDF:filename.nc:variable filename.variable.tif The list of variables (subdatasets) can be obtained from ncdump or gdalinfo. To convert all variables to separate files use: gdalinfo $filename | grep NETCDF | cut -d '=' -f 2 | egrep -v '(lat|lon|time_bounds)' | while read sub do gdal_translate $sub ${filename%.nc}.${sub##*:}.tif done Variable long names, units, PISM configuration parametres and additional information are contained within the netCDF metadata. Also see glacial cycle aggregated and continuous variables. Changes: Version 2: Add variable for glacierized area within 100-m elevation band. Use 100-m instead of 10-m elevation bands for erosion rate.
