AB: Precipitation exhibits significant spatial variability at scales much smaller than the typical size of climate model grid cell. Neglecting such sub-grid variability in climate models causes unrealistic representation of land-atmosphere flux exchanges. We try to tackle this issue by incorporating the satellite-based rain rate observations into the representation of canopy hydrological process in a coupled land-atmosphere model. A static-dynamic approach is used to investigate the impact of the sub-grid variability of rainfall on water cycle through interaction between land surface and atmosphere. To better understand the feedback mechanisms that are responsible for the error propagation caused by the sub-grid variability, various experiments are designed. Preliminary results from this study will be presented.
