Abstract

This study was conducted to estimate vapor supply from irrigated cropland using the hydrological land surface model and the atmospheric water balance method. Based on observation-based meteorological forcing, the authors have estimated vapor supply using the hydrological model: SiBUC. Vapor supply has been also estimated by the atmospheric water balance method using reanalyzed climate data: JRA-25. Vapor supply estimated by SiBUC with irrigation well suits to estimated vapor supply from atmospheric water balance on irrigated land in north China and United States. It suggests that land surface models including irrigation reproduce vapor supply well compared with models including no irrigation.
