NLDAS-2 part of NCEP Central Operations

NOAA implemented the NLDAS-2 system into NCEP Central Operations (NCO) on 5 Aug 2014. The near real-time NLDAS-2 products are available in GRIB-2 format. Operational users are encouraged to use the NCEP/NCO GRIB-2 products. GRIB-1 products, including near real-time updates and a complete archive, will continue to be available at the NASA GES DISC. Note that these GRIB-1 updated products are only available in the NASA GES DISC format. Currently, there is no public archive of the operational GRIB-2 format data from NCEP.

More information about this significant milestone, including the transition of research to operations (R2O), please see this Science Highlight.

LDAS datasets are available from the NASA GES DISC

The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) provides access to LDAS datasets using multiple methods, including HTTPS, GDS, and the ability to subset spatially, temporally, and/or by variable:

These datasets are also available via Giovanni. Giovanni is an online application developed by the GES DISC that allows researchers to rapidly explore data, so that spatial-temporal variability, anomalous conditions, and patterns of interest can be directly and easily analyzed online before optionally downloading the data. Supported download formats include NetCDF, GeoTIFF, and KMZ.
