The definition of the agriculture-sector output variables pirrww and pirruse have been updated to match those in the ISIMIP2b protocol.

pirrww: Irrigation water withdrawal, assuming unlimited fresh-water availability and no water losses during conveyance and application. While the latter assumption has no implications for crop growth, it helps to make reported irrigation water quantities comparable across models.

pirruse: portion of withdrawal that is evapo-transpired, assuming unlimited water supply and no water losses during conveyance and application.
