GAEZ+_2015 Monthly Cropland Data provides crop physical area by month on a global 5-minute grid for 26 crop categories by production system (irrigated and rainfed). Each crop can have up to 5 subcrops to represent crop rotation systems.

Here we provide an update to global gridded monthly crop datasets. This new dataset uses the crop categories established by the Global Agro-Ecological Zones (GAEZ) Version 3 model, which is based on the Food and Agricultural Organization of the United Nations (FAO) crop production data. We used publicly available data from the GAEZ+_2015 Annual global gridded dataset (Frolking et al., 2000) along with data from the MIRCA2000 dataset (Portmann et al. 2008) on crop rotations, cropping intensity, and planting and harvest dates to generate c.2015 monthly crop physical area by crop production system (irrigated and rainfed) for 26 crops and crop categories globally at 5-minute resolution. Each crop category can have up to 5 subcrop categories to represent crop rotations, resulting in a total of 93 individual crop/subcrop/production system combinations (93 files total). These data are in standard georeferenced gridded format (netCDF files), and can be used by any global hydrology, land surface, or other earth system model that requires gridded annual or monthly crop data inputs.
