Summary
Abstract: This data set contains the monthly climatology data of the forcing data for Phase 1 of the North American Land Data Assimilation System (NLDAS-1). The data are in 1/8th degree grid spacing. The temporal resolution is monthly, ranging from January to December. The NLDAS-1 monthly climatology data are the monthly data averaged over the eleven years (1997 - 2007) of the NLDAS-1 monthly data. The file format is WMO GRIB-1.

Brief description about the NLDAS-1 hourly and monthly forcing data can be found from the GCMD DIFs for GES_DISC_NLDAS_FOR0125_H_V001 and GES_DISC_NLDAS_FOR0125_M_V001 at http://gcmd.gsfc.nasa.gov/getdif.htm?GES_DISC_NLDAS_FOR0125_H_V001 and http://gcmd.gsfc.nasa.gov/getdif.htm?GES_DISC_NLDAS_FOR0125_M_V001.

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 Section (PDS) IDs and units.
