Köppen Classification under an acceleration of ice sheets melting under RCP8.5

Maps of Köppen classification are done from Temperature and precipitation obtained by the Global Circulation Model IPSL-CM5A-LR. The model runs under different scenarios: RCP8.5 and ice sheets melting superimposed to RCP8.5.
To reproduce the ice-sheet melting, freshwater is put in the North Atlantic (corresponds to Greenland melting) or around West-Antarctica. Freshwater is introduced between 2020 and 2070 under the RCP8.5 scenario and the total volume corresponds to a sea level rise of 0.5m, 1m, 1.5m and 3m. For the Antarctica and Greenland + Antarctic scenarios, only the 3m scenario is available.

Five time series of Global Köppen classification with 20-year running mean are available in this repository. The maps are produced annually with a resolution of 0.5 ° X0.5 ° and contain the 31 classes of Köppen.

1951 and 2005 for historical run (historical)
2006 and 2099 for RCP8.5 scenarios (RCP85)
2006 and 2099 for Greenland melting (GrIS05m, GrIS1m, GrIS15m, GrIS3m)
2006 and 2099 for Antamelting (WAIS3m)
2006 and 2099 for Greenland melting (GrWAIS3m)

The annual maps are in Geotiff format produced by raster library with R langage. Each Köppen's class corresponds to a number between 0 (sea) and 35. The Excel file (Descriptions of classification.xlsx) give the correspondance between the number and the Köppen classification name (abreviations or full name).
The legendQGIS_Koppen.qpt permits to draw map from each geotiff file with the correct classes and colors with QGIS.
