Improving AquaCrop Root‐Zone Soil Moisture by Assimilating SMAP Surface Soil Moisture

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract Root‐zone soil moisture (RZSM) strongly controls crop development in process‐based crop models, yet most satellite missions observe only near‐surface moisture. We propose a framework to assimilate soil moisture active passive (SMAP) Level‐2 surface soil moisture retrievals into AquaCrop to improve RZSM over European croplands (0.1° resolution,
