warn_icon.gif IMPORTANT MESSAGE Oct 06, 2016    Republishing F16SSMIS, F17SSMIS and F18SSMIS data   

Due to an error, the Precipitation Processing System will reprocess V04 L1-L3 SSMIS data starting with the last orbit of July 18, 2016. The new files will be recognizable bythe "V04B" in the file name.

An error was introduced into the SSMIS L1 products during a small bug fix in July 2016. The 22V cross-pol correction was unexpectedly turned off and caused the 22V channel Tb to be off by 3 - 6 K.

This error also affected the SSMIS L2 – L3 precipitation products.   

Please note that the L2 and L3 Climatology products will also be V04B starting with July 1, 2016. 

If you have already obtained any of these V04A products from our archives or through a Standing order, etc., please discard these and use the replacement V04B products.   

The following orbital products and related browse files will be replaced with V04B data:

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 Nov 23, 2015    Phasing out TRMM Version 6   

GES DISC is in the process of phasing out TRMM Version 6 data that covered the period December 1997 - June 2011. These data were superseded and obsoleted by the much improved Version 7. We also do remind that data from the TMPA Version 7 are still produced, even though the TRMM satellite was decommissioned in April, and deorbited in June, 2015. The Version 6 data will first be reduced in visibility in web search engines  and documentation, and then physically removed from the on-line archives by the end of February, 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.

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.
