This dataset consists of a netCDF file with a number of layers at half-degree global resolution. Each layer is a binary map representing whether each gridcell is included (1 if yes, 0 if no) in one or more input datasets used in the ISIMIP3 Agriculture (GGCMI phase 3) model runs. Individual-dataset masks: has_soil indicates inclusion in the ISIMIP3 soil input dataset (Volkholz & Müller, 2020) (ignoring "gravel," which has some missing cells). has_cropcals indicates inclusion in the Jägermeyr et al. (publication in prep.) crop calendar dataset (ignoring second-season rice, which is not grown in all gridcells). has_lu indicates inclusion in all 15 area maps in the historical land use area dataset prepared for ISIMIP3 (landuse-totals_histsoc_annual_1850_2014.nc). has_crops indicates inclusion in all 15 area maps in the historical 15-crop dataset prepared for ISIMIP3 (landuse-15crops_histsoc_annual_1850_2014.nc). Note that there are two gridcells that are missing from this has_fertilizer indicates inclusion in every fertilizer_application_histsoc*.nc file in the fertilizer and manure dataset prepared by Heinke et al. (2021) for GGCMI3. has_all is a composite mask indicating inclusion in all of the above. Also included are a figure showing the masks and the MATLAB script used to generate the data and figure.
