File names:

ciscyc4.{10km|5km}.{forcing}.{ex.100a|ex.1ka|ts.10a}.nc

Horizontal resolution:

10km: 10 km horizontal resolution

5km: 5 km horizontal resolution

Temperature forcing:

epica: EPICA ice core temperature forcing

grip: GRIP ice core temperature forcing

ngrip: NGRIP ice core temperature forcing

odp1012: ODP 1012 ocean core temperature forcing

odp1020: ODP 1020 ocean core temperature forcing

vostok: Vostok ice core temperature forcing

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.

Changelog:

Version 2:

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

Version 1:

Initial version.
