Data News

PPS will start to process the TRMM TMI level 2 and level 3 GPROF products, the core member of the TRMM era GPROF products family, on Thursday, April 19, 2018. Similar to the early released TRMM era AMSRE, AMSUB, SSMI, MHS, SSMIS, AMSR2 and ATMS level 2 and level 3 products, all level 2 and level 3 GPROF products will be produced as GPM version V05, all products are in HDF5 format, all product names will use the GPM naming convention and the produced data will appear both in STORM:
https://storm.pps.eosdis.nasa.gov/storm/
and on "arthurhou":
ftp://arthurhou.pps.eosdis.nasa.gov/
after these are produced.

The retrieval algorithm complies with those used for other GPM Version 5 products. As compared to TRMM V7, the GPM V05 TMI precipitation field has a much better match with the GPM V05 GMI precipitation field for the TRMM-GPM overlap time period. The detailed Algorithm documentation can be reviewed at https://pps.gsfc.nasa.gov/Documents/ATBD_GPM_V5B_April15_2018.pdf

All users are encouraged to retrieve these latest TMI level 2 and level 3 GPROF products to ensure that they use the most recent products. The TMI level 2 and level 3 GPROF products being reprocessed is listed below with its data source, start time and end time:

Data Source                                        Start of Data                                    End of Data

The other note is that the GANAL ancillary data is not available back through the TRMM era. So only the GPROF products using the ECMWF ancillary data will be produced.

When the TMI level 2 and level 3 GPROF products are processed, the reprocessing of the GPM version V05 GPROF products for the entire TRMM era will be completed. PPS will continue to work with the GPROF researcher and algorithm developer community. Once there is any updated GPROF product available, PPS will inform users as soon as possible.

As always, the processed TRMM TMI level2 and level 3 GPROF products will be held until they have been reviewed and verified by the Science Team.  The processed TRMM TMI level 2 and level 3 GPROF products will be released to the public upon their approval.

The Level 2 GPM Precipitation Retrieval and Profiling Scheme (PRPS) product for SAPHIR on the Megha-Tropiques satellite are available both in STORM:
https://storm.pps.eosdis.nasa.gov/storm/
and on "arthurhou":
ftp://arthurhou.pps.eosdis.nasa.gov/

The SAPHIR PRPS products have been processed back to data date October 13, 2011.  NASA requires users to register at: https://registration.pps.eosdis.nasa.gov/registration/
 to access PPS data services.

The Level 2 PRPS product is a new member of the GPM Level 2 product family. It is intended to exploit the capabilities of the passive microwave sounding instruments of the GPM constellation. The PRPS Algorithm Theoretical Basis Document (ATBD) can be found on the PPS public website at https://pps.gsfc.nasa.gov/atbd.html.

Other documentation can be found at https://pps.gsfc.nasa.gov/ppsdocuments.html and https://pps.gsfc.nasa.gov/GPMprelimdocs.html on the PPS public website https://pps.gsfc.nasa.gov/

Effective 27 January 2018 all the IMERG Early products have a retrospective V05B processing for the entire GPM mission starting in March 2014. All V04 products have been saved in a V04 directory. V03 products are no longer available.

Effective 27 January 2018 IMERG Late products have a retrospective V05B processing from the beginning of the mission in March 2014 to January 2017.  We continue to process Late products and they should be completed in another week.

We are also working on retrospective processing to V05B of the GIS friendly TIFF IMERG based products.  These should all be at V05B in approximately 3 weeks from this message date.

On 26 January starting 08:00 UTC, PPS began regularly processing a precipitation retrieval from the SAPHIR cross-track scanning radiometer on the Megha-Tropiques mission. These products are available on the PPS NRT server (jsimpson) in the /NRTPUB/PRPS directory.  The Algorithm Theoretical Basis Document (ATBD) is not currently available but will be provided within a week. It will be located in /NRTPUB/documentation.  The file specifications can be retrieved from the website pps.gsfc.nasa.gov.

On 1 December 2017 sometime between 07:00 UTC and 12:00 UTC, PPS will begin installing V05B algorithms for the near realtime (NRT) IMERG dataset. If no problems arise, the installation should take approximately 4 hours. During this period IMERG products will be unavailable.

While this is the first V05 IMERG available from NRT, we are making the data product version V05B so that both the early and the late product will be consistent with the version of the final product which is at V05B.

To avoid unnecessary emails, PPS will not send out an email when the V05 installation is complete.  Users will know installation is complete when they see 1 December 2017 V05B data products available.

When the installation is complete PPS will ensure that all products from 1 December 2017, 00UTC are at V05B.  IMERG products before that date/time will remain at V04A.

The current schedule calls for the retrospective processing of all NRT data, both early and late, to begin in January of 2018.

Please contact us for any questions.

Starting the week of November 20, PPS will generate and release Version 05B of the GPM IMERG Final products.  The Version 05A GPM IMERG Final products with data dates between March and October 2014 products are valid HDF5 science products.  However, these products yield errors when opened with NetCDF4 utilities and library.

To satisfy the requirements of the NetCDF4 users, PPS will release Version 05B GPM IMERG Final products starting next week.  All the contents, data format, data server address and documents are unchanged.  If you are a HDF5 user, you can keep using these Version 05A products or retrieve the new Version 05B IMERG Final products depending on your preference.  If you are a NetCDF4 user, please use this Version 05B GPM IMERG final products, and refer to the data server and documents in the release announcement of the Version 05A GPM IMERG Final products.

Please note that processing begins with the earliest IMERG datasets (beginning with March 2014) and it takes several weeks to fully populate the directories, so users may not see the V05B products immediately.

Please contact us for any questions.
