title: Alpine ice sheet erosion potential aggregated variables

description: 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. Seguinot and I. Delanay. Last glacial cycle glacier erosion potential in the Alps, <em>submitted to Earth Surface Dynamics Discussions</em>, 2021. <strong>File names:</strong> <pre><code>alpero.{1km|2km}.{epic|grip|md01}.{cp|pp}.agg.nc</code></pre> Horizontal resolution: <em>1km</em>: 1 km horizontal resolution <em>2km</em>: 2 km horizontal resolution Temperature forcing: <em>epic</em>: EPICA ice core temperature forcing <em>grip</em>: GRIP ice core temperature forcing <em>md01</em>: MD01-2444 core temperature forcing Precipitation forcing: <em>cp</em>: constant precipitation <em>pp</em>: palaeo-precipitation reduction <strong>Variables:</strong> Coordinate variables: <em>x</em>: X-coordinate in Cartesian system <em>y</em>: Y-coordinate in Cartesian system <em>lon</em>: longitude <em>lat</em>: latitude <em>time</em>: time <em>age</em>: model age <em>z</em>: elevation band midpoints <em>d</em>: distance along transect Glacier erosion variables: <em>coo2020_cumu</em>: Cook et al. (2020) cumulative glacial erosion potential <em>coo2020_rate</em>: Cook et al. (2020) domain total volumic erosion rate <em>coo2020_hyps</em>: Cook et al.

(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.
