Global gridded crop model ACEA

Research output: Non-textual formSoftwareAcademic

Abstract

AquaCrop-Earth@lternatives (ACEA) is a global gridded crop model that can estimate crop yield and evapotranspiration (ET) distinguishing three water types: green water, blue water from capillary rise, and blue water from irrigation. ACEA is based on AquaCrop-OSPy (Kelly and Foster, 2021) which simulates daily crop growth and the vertical soil water balance using crop, soil, climate, field and irrigation management data. The 2.0 version was recently applied to simulate the water footprints of 175 crops in 1990–2019 (Mialyk et al., 2023). For the detailed model description, please refer to Mialyk et al. (2022). For instructions, please refer to Readme.pdf. Some technical information is provided below: Programming language Python Core model AquaCrop version 6.1 Resolution 5 or 30 arcminutes (global, national, separate grid cells) Number of supported crops 55 (e.g. rice, wheat, tomatoes, soybeans, apple, coconut etc) Main inputs Global annual CO2; gridded daily climate; gridded soil and groundwater data; crop-specific parameters (some are gridded); subnational crop calendars; gridded rainfed and irrigated harvested areas Extra features Green-blue water accounting, water footprint calculation, parallel computation
