abstract: "<p><strong>Overview</strong></p><p>Here we provide outputs of the global simulation of water footprints of crops with a process-based gridded crop model ACEA (see model description in the references). The model is based on FAO’s AquaCrop and covers 175 widely-grown crops in the 1990–2019 period at a 5 arcminute resolution (10 x 10 km). We partition water footprints into green (water from precipitation) and blue (from irrigation or capillary rise) and differentiate between rainfed and irrigated production systems. The outputs cover several variables, including unit water footprints (expressed in m<sup>3</sup> t<sup>-1</sup> yr<sup>-1</sup>), water footprints of crop production (m<sup>3</sup> yr<sup>-1</sup>), and crop water use (mm yr<sup>-1</sup>).
