Mission Updates

GPM V05 Data Announcement and IMERG

The Precipitation Processing System has begun the transition to GPM Version 5 products.

The satellite observations made in April 2017 will be the last observations to be included in Version 4 of the GPM data products, with one exception. Starting with observations made in May 2017, PPS will generate Version 5 GPM data products, again with one exception.  The exception in both cases is that  the PPS Realtime system will continue to generate the Version 4 Early and Late IMERG data products.  Version 4 data products have been removed from the STORM data ordering system (https://storm.pps.eosdis.nasa.gov/storm/ to make room for Version 5 data products).  Version 4 data products,  however, will continue to be available for download from the GPM's "arthurhou" FTP archive or from the "jsimpson" FTP archive in the case of Early and Late IMERG.

GPM V04 standing orders and stand-alone orders will be processed and distributed through April 30th, 2017. Starting with data date May 1, 2017 all products will be produced as V05. With the start of V05 processing the V04 data will only be accessible from the arthurhou FTP archives (ftp://arthurhou.pps.eosdis.nasa.gov/gpmallversions/V04/). As V05 products become available later this month, they will appear in STORM and on "arthurhou".

The PPS Toolkit for GPM V05 products is tkio-3.80.26 and is also backwards compatible with V04 products.

On Tuesday May 02, 2017, PPS will complete GPM and Partner V04 products. All GPM and Partner V04 products will be processed through data date April 30, 2017 with the exception of the following:

  • IMERG Final Run V04, which is still in production, will end with data date Feb 28, 2017.
  • IMERG Early and Late Run will continue to be produced as V04, using V05 GPM inputs. 
  • -L2-L3 GPROF Climatology products will end with data date Jan 30, 2017.

PPS will reprocess the entire mission as V05 starting with March 2014 data. All users should transition to the improved V05 products to ensure that they are using the latest algorithms.

All V05 data products will be held until they have been reviewed and verified by the Science Team. GPM V05 Products will be announced and released to the public upon their approval.

Users with standing orders will experience an interruption in data delivery as we make our transition to GPM and partner V05 production.

GPM V05 release notes and other documentation will be available through our ftp archives and the PPS public website prior to the public release. We will include this information in a future announcement.

Please contact us if you have any concerns, comments or questions.

Thank you for your patience during this transition.
