High resolution land data assimilation system (hrldas) is an off-line driving force of land surface model existing in weather research and prediction (WRF) model. Hrldas uses a combination of observational and analytical measurements (precipitation, solar and longwave radiation, and surface wind, humidity, and temperature) to drive land surface models to simulate the evolution of land surface conditions (e.g., soil moisture and temperature, snow, etc.). The system has been developed and can run on the WRF domain or multiple site locations.
