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

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.
