Abstract
A high-resolution land data assimilation system (HRLDAS) was developed and was applied to a coupled modeling system, the weather research and forecast (WRF). The aim of the system was to reduce the errors introduced by interpolating land conditions from one LDAS source to a coupled model grids because of the mismatch of terrain, landuse, and soil specifications. As an example, HRLDAS was set up to run in the continental US due to the readily available forcing data required by HRLDAS in this region. The results show that the HRLDAS compares well with Mesonet and IHOP soil moisture in terms of seasonal tendency, and the correct specification of soil texture in HRLDAS is critical for comparing HRLDAS results with observations.
