Abstract

The aim of this study is to propose a 20km resolution global water cycle model in land including irrigation. In recent years, water cycle models are proposed to understand the impact of climate change on water resources and water cycle at global scale. Those models, which simulate at a spatial resolution from 0.5 to 1.0 degree, have possibilities not to describe water flow accurately at basin scale. In contrast to previous models, our model sets three originalities. First, water cycle in land is analyzed at 20km resolution. Second, irrigation water requirement is analyzed physically with hydrological land surface model. Third, cropping calendar is specified from phonological analysis of remote sensing data. In this paper, we describe model structure and discuss its accuracy of analysis.
