These data contain time-integrated and otherwise time-reduced glacier model output variables.

File names: alpcyc.{1km|2km}.{epic|grip|md01}.{cp|pp}.agg.nc Horizontal resolution: 1km : 1 km horizontal resolution 2km : 2 km horizontal resolution Temperature forcing: epic : EPICA ice core temperature forcing grip : GRIP ice core temperature forcing md01 : MD01-2444 core temperature forcing Precipitation forcing: cp : constant precipitation pp : palaeo-precipitation reduction 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 continuous variables. Changelog: Version 2: Add age coordinate in kiloyears (ka) before present. Use ka units for covertime, deglacage and maxthkage.
