Data News

On Sunday June 17, 2018 PPS System Programmers and staff will be performing an important scheduled GPM archive server upgrade.

Due to this upgrade process, most PPS systems and services will be unavailable for most or all of that day starting at 9:00 AM (EDT) and lasting until late afternoon or longer depending upon the upgrade circumstances.

-It is important to note that GPM (NRT) near realtime services  (SDPS and ftp://jsimpson.pps.eosdis.nasa.gov/) will remain available and unaffected during this  period.
-PPS's Aeolus server (ftp://aeolus.pps.eosdis.nasa.gov/)  will only provide near real time products during this maintenance period.

PPS Systems and Services that will be unavailable include the following:

-PPS Production
-Hydra server
-PPS FTP data archive (ftp://arthurhou.pps.eosdis.nasa.gov/)
-PPS User Registration (https://registration.pps.eosdis.nasa.gov/registration/)
- STORM (https://storm.pps.eosdis.nasa.gov)  PPS Online Data Ordering Interface
-PPS Public Website (https://pps.gsfc.nasa.gov/)
-PMM Public website (https://pmm.nasa.gov/)

We will keep you informed in regards to any changes or delays.   We apologize for any inconvenience that this may have caused and appreciate your patience during this period.

Please contact us if you have any questions or concerns.

The STORM Swath-Based Analysis Tool (https://storm.pps.eosdis.nasa.gov/storm/Analysis.jsp) is a better way to explore and order targeted Level 2 data. Select one or more instruments from a list going back to the beginning of the TRMM mission, provide a date range, and input a geographic region of interest. Once you hit "Get Granules for Chart," a graph will appear and data points will begin to display. These points represent the mean precipitation rate value for all of the pixels for that orbit of that instrument over that geographic region.

Once the graph loading is paused or complete, interact with the graph by changing the statistical value displayed and the colors used to represent them. The points themselves are also interactive, with the ability to download full granules with couple clicks, or visualize these overflights in THOR Orbit Viewer and STORM Virtual Globe. Once you have a statistical threshold of interest, create a geographically subset order of only those overflights that meet or exceed that threshold.

With the Swath-Based Analysis Tool, get the events you want for the regions you want. For more detailed information on using the Swath-Based Analysis Tool, check out Section 3 of the STORM User Guide https://storm.pps.eosdis.nasa.gov/storm/STORMUserGuide.pdf

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 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.

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.
