File names:

alpcyc.{1km|2km}.{epic|grip|md01}.{cp|pp}.{ex.100a|ex.1ka|ts.10a}.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

Variable types:

ex.100a: spatial diagnostics every hundred years

ex.1ka: spatial diagnostics every thousand years

ts.10a: scalar time-series every ten years

Data format: The data use compressed netCDF format. For quick inspection I recommend ncview. Spatial diagnostics (*.ex.*.nc) can be converted to GeoTIFF (and other GIS formats) e.g. using GDAL:

gdal_translate NETCDF:filename.nc:variable -b band filename.variable.band.tif

The list of variables (subdatasets) can be obtained from ncdump or gdalinfo. The band number equals 120 minus the age in ka. Band information can be displayed with:

gdalinfo NETCDF:filename.nc:variable

Variable long names, units, PISM configuration parametres and additional information are contained within the netCDF metadata. Also see aggregated variables.

Changelog:

Version 3:

Add spatial diagnostics every hundred years (*.ex.100a.nc)

Version 2:

Add age coordinate in kiloyears (ka) before present.

Replace NCO by Xarray workflow (no effect on the results).

Version 1:

Initial version.
