| Summary: | These data contain a subset of time-dependent glacier model output variables. The ghf70 data files are an update on the reference below, fixing significant problems affecting the computation of the bedrock deformation in response to ice load (PISM Github issues #370 and #377 ) and the computation of ice temperature (PISM Github issue #371 ). The other data files additionally include spatially-variable geothermal heat flux ( dav13 , gou11comb , gou11simi , sha04 ), different lithospheric rigidity ( eet30km ) or mantle viscosity ( num1e21 ), and higher horizontal resolution ( 3km ).

For quick inspection I recommend ncview. Spatial diagnostics ( *.ex.100a.nc ) can be converted to GeoTIFF (and other GIS formats) e.g. using GDAL: <code>gdal_translate NETCDF:filename.nc:variable -b band filename.variable.band.tif</code> The list of variables (subdatasets) can be obtained from ncdump or gdalinfo. Band information can be ...
