warn_icon.gif IMPORTANT MESSAGE Apr 24, 2014    NLDAS Phase 2 VIC Model Data Sets Released by NASA GES DISC    

This release includes three sets of NLDAS-2 VIC model data: hourly, monthly, and a monthly climatology. Information on and access to these data are available at http://disc.sci.gsfc.nasa.gov/datareleases/nldas_phase_2_VIC_model_release.

warn_icon.gif IMPORTANT MESSAGE Apr 14, 2014    GLDAS-2.0 data reprocessing is completed   

Update May 14, 2014: The reprocessing for GLDAS-2.0  Noah data sets is completed. The data can be accessed from the Hydrology Data Holdings Portal. Please note that the reprocessed 0.25 degree 3-hourly files have a new file name convention as GLDAS_NOAH025_3H.AYYYYMMDD.HH00.020.grb and GLDAS_NOAH10_3H.AYYYYMMDD.HH00.020.grb (the file production time has been dropped from the file name, but kept in the corresponding metadata xml file).

A reprocessing of GLDAS Version 2.0 (GLDAS-2.0) data is ongoing. This reprocessing is to resolve an output precision issue associated with the variable, specific humidity. Therefore, only the variable, specific humidity, is affected; all other variables remain unchanged. For the period of reprocessing, the GrADS Data Server (GDS) has been disabled for the GLDAS-2.0 data set. Other data access methods remain available.

The GDS will be re-enabled after the reprocessing has been completed. As an estimate, it may take about three weeks to complete the reprocessing. Thanks a lot for your patience.

Supporting the Hydrological Sciences Laboratory (HSL)

The Hydrology DISC supports data products generated by GSFC's Hydrological Sciences Branch. Data products from the North America Land Data Assimilation System (NLDAS) and the Global Land Data Assimilation System (GLDAS) can  be accessed through anonymous ftp, the Mirador search and access tool or the GrADS Data Server (GDS). NLDAS and GLDAS systems integrate data from multiple space-based Earth observing systems using advanced land surface modeling and assimilation techniques. These products support weather and climate forecast experiments, water resources applications, and water and energy cycle research.

The data are provisional and subject to change as model improvements are implemented and new input data sets become available.

Other atmospheric moisture and precipitation products are available from the AIRS and Precipitation Data and Information Services Centers.
