We are contacting you to report an problem where Version 4 GPM data products could not be read using the 4.2.2.1 version of netCDF.  Users are recommended to upgrade to netCDF 4.3.3.1 or later. Any software (OPeNDAP, etc.) that uses older than netCDF Version 4.3.3.1 (what we tested, versions earlier in the 4.3 series may also work) will not be able to read GPM DF5 Version 4 data.

The PPS (Precipitation Processing System) will be down today, June 07, 2016 from 8:00am -14:00pm EDT (12:00 - 18:00 UTC). for scheduled maintenance. During this time all data transfers between PPS source and its consumer systems (GDAAC/DISC) as well as Science User services (FTP and STORM access) will be unavailable. You will be informed when PPS systems become available. We apologize for any inconvenience this may cause.

With the GPM Version 04 Update, PPS is also rolling out an interactive GPM  NRT Viewer. This tool displays NRT Level 1C GMI, Level 2A GPROF, and Level 2A  DPR data as soon as it is available in the NRT archive on a three-dimensional  globe.  Fields such as brightness temperature and surface precipitation rate are  available for visualization, comparison, and improved data acquisition  decision-making.  You may Leave it running continuously as data refreshes...

Due to continuing, intermittent anomalies in the F17 SSMIS 37v channel, starting from April 13, 2016 (Orbit # 48713 : 18:29:36) and forward all 1C F17 products will flag the 37V channel as bad data and the Brightness Temperatures will be missing. We apologize for any inconvenience or problems that this may cause and appreciate your understanding and patience. Please let us know if you have any questions or concerns. 
The Precipitation Processing System (PPS) is currently experiencing a hardware problem which is impacting PPS data production,  ftp archive access (arthurhou, trmmopen, etc.),  and PPS web sites (STORM, THOR, etc.) today - Tuesday May 10,2016. Our system programmers are currently working on this problem and hope to restore services as soon as possible.  We will keep you informed as the situation changes. We apologize for any inconvenience that this may have caused and...

PPS will be restarting F17 processing. There will be 88 1C products that will be retracted and reprocessed for the following dates: 2016-04-13 (18:29:37)  to 2016-04-19 (23:56:53). Starting from this date and forward all 1C F17 products will flag the 37V channel as bad data and the Brightness Temperatures will be missing. We apologize for any inconvenience or problems that this may cause and appreciate your understanding and patience. Please contact us if you have any questions...

V04 Processing processing of GMI GPROF retrievals began at 11:20 UTC, May 2. Please note the the GPM Near-realtime (NRT) subsystem began to run the V04A GPROF precipitation retrieval effective 11:20UTC, May 2, 2016.   Information about changes in the version can be found in the document GMI.V4.Release.Notes_05.01.2016.pdf that is located in directory  /NRTPUB/V4ReleaseInfo The biggest change in the retrieval is the use of an a-priori database constructed...
