Alpine ice sheet glacial cycle simulations aggregated variables
收藏资源简介:
These data contain time-integrated and otherwise time-reduced glacier model output variables. <strong>Reference:</strong> Seguinot, J., Ivy-Ochs, S., Jouvet, G., Huss, M., Funk, M., and Preusser, F.: Modelling last glacial cycle ice dynamics in the Alps, <em>The Cryosphere</em>, 12, 3265-3285, doi:10.5194/tc-12-3265-2018, 2018. <strong>File names:</strong> <pre><code>alpcyc.{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>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 continuous variables. <strong>Changelog:</strong> Version 2: Add age coordinate in kiloyears (ka) before present. Use ka units for covertime, deglacage and maxthkage. Version 1: Initial version
