This dataset contains BIOCLIM variables (plus gdd5 and gsl5) which have been prepared and calculated from the original ISIMIP3b bias-adjusted climate forcing data from 4 (for ssp119), respectively 5 GCM models (obtained on 2024-03-24). For more information on the original data and its properties, please see the ISIMIP3b modelling protocol and here specifically the climate forcing section https://protocol.isimip.org/#/ISIMIP3b/31-forcing-data and Frieler et al. (2024). The original climate forcing data (global extent, daily temporal grain) were masked to a global land mask and spatial-temporally aggregated. Here 10 year (decadal) steps were chosen as target climatology.For each time slot (e.g. 10 years) and scenario (historical or ssps) the following 21 variables were calculated: bioclim01 = Annual Mean Temperaturebioclim02 = Mean Diurnal Range (Mean of monthly (max temp - min temp))bioclim03 = Isothermality (BIO2/BIO7) (×100)bioclim04 = Temperature Seasonality (standard deviation ×100)bioclim05 = Max Temperature of Warmest Monthbioclim06 = Min Temperature of Coldest Monthbioclim07 = Temperature Annual Range (BIO5-BIO6)bioclim08 = Mean Temperature of Wettest Quarterbioclim09 = Mean Temperature of Driest Quarterbioclim10 = Mean Temperature of Warmest Quarterbioclim11 = Mean Temperature of Coldest Quarterbioclim12 = Annual Precipitationbioclim13 = Precipitation of Wettest Monthbioclim14 = Precipitation of Driest Monthbioclim15 = Precipitation Seasonality (Coefficient of Variation)bioclim16 = Precipitation of Wettest Quarterbioclim17 = Precipitation of Driest Quarterbioclim18 = Precipitation of Warmest Quarterbioclim19 = Precipitation of Coldest QuarterGDD5 = Mean annual growing degree days above 5C using daily mean temperature ((tasmax + tasmin) / 2)GSL5 = Mean annual longest consecutive run of days with daily mean temperature above 5C ---Data properties: Shared Socioeconomic Pathways (SSP) SSP1-1.9, SSP1-2.6, SSP2-4.5, SSP3-7.0, SSP5-8.5 General circulation models (GCMs) GFDL-ESM4, IPSL-CM6A-LR, MPI-ESM1-2-HR, MRI-ESM2-0, UKESM1-0-LL Spatial grain 0.5 degree (~50km²) Geographic projection WGS 84 Temporal grain 10 year steps Spatial extent Global (see screenshot) Temporal extent 1850 to 2010 (Historical), 2010 - 2100 (Future) Number of variables 21 All files are provided in netCDF (nc) format.
