Description

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

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.
