Alpine ice sheet erosion potential aggregated variables

These data contain domain-integrated and time-integrated model output variables presented in the reference below or otherwise relevant to last glacial cycle glacier erosion in the Alps. <strong>Reference:</strong> J.

(2015) erosion rate geometric mean <em>kop2015_rhin</em>: Koppes et al. (2015) rhine transect erosion rate Other variables: <em>cumu_sliding</em>: cumulative basal motion <em>glacier_time</em>: total ice cover duration <em>warmbed_time</em>: temperate-based ice cover duration <em>glacier_area</em>: glacierized area <em>volumic_lift</em>: volumic bedrock uplift <em>warmbed_area</em>: temperate-based ice cover area <strong>Data format:</strong> The data use compressed netCDF format. For quick inspection I recommend ncview. Conversion to GeoTIFF (and other GIS formats) can be achieved with e.g. GDAL:: <pre><code>gdal_translate NETCDF:filename.nc:variable filename.variable.tif</code></pre> The list of variables (subdatasets) can be obtained from ncdump or gdalinfo. To convert all variables to separate files use: <pre><code>gdalinfo $filename | grep NETCDF | cut -d '=' -f 2 | egrep -v '(lat|lon|time_bounds)' | while read sub do gdal_translate $sub ${filename%.nc}.${sub##*:}.tif done</code></pre> Variable long names, units, PISM configuration parametres and additional information are contained within the netCDF metadata. Also see glacial cycle aggregated and continuous variables. <strong>Changes:</strong> Version 2: Add variable for glacierized area within 100-m elevation band. Use 100-m instead of 10-m elevation bands for erosion rate. Version 1: Initial version.
