Description
These data contain a subset of time-dependent glacier model output variables:

File names:
ciscyc4.{10km|5km}.{forcing}.{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.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.1ka.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.
