Unified Noah LSM
The Community Noah Land-Surface Model (LMS)
Unified WRF-Noah LSM
RAL scientists work to understand, through theoretical and observational studies, the complex biophysical, hydrological, and bio-geochemical interactions between the land-surface and the atmosphere at micro- and mesoscales. The ultimate goal is to integrate such knowledge into numerical mesoscale weather prediction and regional climate models to improve prediction of the impacts of land-surface processes on regional weather, climate, and hydrology. Land surface modeling efforts were funded in FY06 by NSF, the Air Force Weather Agency (AFWA), NOAA, NASA, and DTRA.
