Summary
Abstract: This data set contains a series of land surface parameters simulated
from the Noah land-surface model (LSM) for Phase 2 of the North
American Land Data Assimilation System (NLDAS-2). The data are in
1/8th degree grid spacing and range from Jan 1979 to the present.
The temporal resolution is hourly. The file format is WMO GRIB-1.

Details about the NLDAS-2 configuration of the Noah LSM can be
found in Xia et al. (2012).

The Noah model was developed as the land component of the NOAA NCEP
mesoscale Eta model [Betts et al. (1997); Chen et al. (1997); Ek et
al. (2003)]. As used in NLDAS-2, recent modifications were made to
Noah's cold-season [Livneh et al. (2010)] and warm-season [Wei et
al. (2012)] parameterizations. Noah serves as the land component in the
evolving Weather Research and Forecasting (WRF) regional atmospheric
model, the NOAA NCEP coupled Climate Forecast System (CFS), and the
Global Forecast System (GFS). The model simulates the soil freeze-thaw
process and its impact on soil heating/cooling and transpiration,
following Koren et al. (1999). The model has four soil layers with
spatially invariant thicknesses of 10, 30, 60, and 100 cm. The first
three layers form the root zone in non-forested regions, with the fourth
layer included in forested regions.

The Noah LSM was forced by the hourly NLDAS-2 forcing "File A" files,
and contains fifty-two fields. The data set applies a user-defined
parameter table to indicate the contents and parameter number. The
following table shows a list of parameters, their Product Definition
