Unified 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.

Vegetation and Soil Parameters

        Noah LSM uses three tables: VEGPARM.TBL, SOILPARM.TBL, and GENPARM.TBL. The tables are read in module_sf_noahlsm.F. Copies of the tables and brief descriptions of the parameters are provided here:
General parameters-- GENPARM.TBL-- (documentation)
Soil Parameters-- SOILPARM.TBL-- (documentation)
Vegetation Parameters-- VEGPARM.TBL-- (documentation)
