This dataset contains 147 monthly aquaculture and irrigation water-use rasters output by AIWUM 1.1 for each month of the growing season (April-October) for each year in the model period (1999-2019). Pixel value units are in cubic meters per square kilometer. Aquaculture and irrigation water-use estimates are included in this data release in two different formats: georeferenced TIFFs (GeoTIFFs) for simple viewing and geospatial operations (Monthly_total.zip) and a network common data form (NetCDF) for use in modeling applications and with each month as a separate raster array table (irr_wu_1km_1999_to_2019.zip).
