The data consist of 15 annual extreme indices on the entire world and given in a geo-tiff raster datasets. These jndices depend on daily precipitation or daily temperature simulated by the Global Circulation Model (GCM) IPSL-CM5A-LR used in the Coupled Model Intercomparison Project Phase 5 (CMIP5). A historical run and seven different climatic scenarios are simulated between 1951 and 2006 (historical) and between 2006 and 2099 (climatic scenarios). The first climatic scenario is the RCP8.5 baseline scenario from The Intergovernmental Panel on Climate Change (IPCC) corresponds to a global temperature increase of ~5°C with respect to the pre-industrial level. The six other scenarios are superimposed on the RCP8.5 scenarios with an input of freshwater from Greenland and/or West-Antarctica added in the ocean. The amount of added freshwater corresponds to 1.5 or 3m of sea level rise. The results are seven annual time series of the 15 indeces across the world with a 0.5°X0.5° resolution (~50x50 km at the equator) and an historical run from 1951 to 2005. For each grid cell, we have seven different annual evolutions of each index by the end of 21st century. RCP8.5 scenario corresponds to the entire period from 1951 to 2099. For the other scenarios, it is only from 2006 to 2099. The period from 1951 to 2099 corresponds to the historical run (rcp8.5).
