North American Land Data Assimilation System (NLDAS)

0.125 degree Hourly Products


Home
North American Land Data Assimilation System (NLDAS) is generating a series of land surface forcing (e.g, precipitation, surface meteorology and radiation), state (e.g., soil moisture and temperature, and snow), and flux (e.g., evaporation and sensible heat flux) products simulated by four land surface models (SAC, Mosaic, Noah and VIC).

Current data holdings include a set of 0.125 degree resolution data products from forcing data and Mosaic and Noah models, covering 1979 to the present. This instance focuses on NLDAS Phase 1 and Phase 2 0.125 degree hourly products.

2012-03-28: Please notice that NLDAS Phase 2 NOAH Model data set, NLDAS_NOAH0125_H.002, is now available in this portal.
