Description

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 (Mialyk et al., 2022). The 2.0 version was recently applied to simulate the water footprints of 175 crops in 1990–2019 (Mialyk et al., 2024).

For the detailed model description, please refer to Mialyk et al. (2022). For instructions, please refer to Readme.pdf.
