warn_icon.gif IMPORTANT MESSAGE Jul 18, 2016    GES DISC TRMM archive maintenance   

 

 The GES DISC TRMM archive is currently undergoing a substantial upgrade. It encompasses installation of new hardware and software, transition to Common Metadata Repository and User Registration System,  transition from external to internal HDF4-compression, and case-by-case revision of all products that will continue to be supported. All of these impose competing demands and may result in short interruptions of TRMM data services in Mirador, Simple Subset Wizard, and Giovanni. However, no interruptions are expected in the on-line access and download of TRMM data from http://disc2.gesdisc.eosdis.nasa.gov/data

These activities are expected to be finalized by August 3, 2016.    

warn_icon.gif IMPORTANT MESSAGE Jul 24, 2015    Why do my Data Holdings look different?    

Accessing your data through the GES DISC web site may seem a little unfamiliar to you to these days, but we can assure you, your data is all still available. The location of the data in the online archive has not changed.

The GES DISC has implemented a new interactive interface to make finding data easier than ever. We've added features like searching by keywords, filtering by criteria such as measurements, processing level and spatial resolution, and sortable data columns so now you can fine tune your search results. To get you started we put together a Help document to introduce you to the new interface. If you have any questions about the new design please contact us using the Feedback link in the upper right-hand corner or contact the GES DISC Help Desk by sending email to gsfc-help-disc@lists.nasa.gov.

Supporting the Hydrological Sciences Laboratory (HSL)

The Hydrology DISC supports data products generated by GSFC's Hydrological Sciences Laboratory (HSL). Data products from North America Land Data Assimilation System (NLDAS),  Global Land Data Assimilation System (GLDAS), and Famine Early Warning Systems Network (FEWS NET) Land Data Assimilation System
(FLDAS) can  be accessed through http, the Mirador search and access tool or the GrADS Data Server (GDS). The LDAS 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.
