Data format:
The data use compressed netCDF format. 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.
