Data News

PPS is releasing version 3.80.44 build of the PPS TKIO toolkit using the 14.0.1 Fortran compiler for GPM. As detailed in our earlier announcement that you received on Thursday, June 28th, 2018, titled;

"PPS is Reprocessing TRMM PR Data as TRMM GPM, Version 06A HDF5 products in Early July 2018"

This is the version of the PPS I/O Toolkit that will be used for these radar products.

The release notes are in this directory and are also attached to this

The TRMM Version 7 Precipitation Radar (PR) products will be superseded by new GPM era products with a reprocessing that will generate TRMM retrievals from the beginning of the TRMM mission to the end of data collection using a single frequency retrieval algorithm similar to that used for GPM Ku. This reprocessing will begin in early July, 2018.

Retrievals previously available in the TRMM Version 7 products 2A21, 2A23, 2A25, and 3A25 will be available in the new 2APR and 3PR products. Note that these new GPM era products are in HDF5 format and similar in structure to those used for GPM DPR products. Please see the TRMM HDF5 Primer <https://pps.gsfc.nasa.gov/Documents/TRMM_HDF5_Primer.pdf> for information on moving from TRMM Version 7 HDF4 products to TRMM GPM Version 06A HDF5  products. Many third party tools such as IDL and Matlab have native routines to read HDF5 data.

The Version of the PPS I/O Toolkit used will be TKIO 3.80.44 or later for these radar products.  A separate announcement will be sent for those using the TKIO to access the HDF data products. 

In order to synchronize processing versions with the upcoming GPM DPR
reprocessing (06A) the new TRMM radar products will also be Version V06A.

Note that PPS STORM data ordering is only applicable to the latest processing version and TRMM Version 7 data will be removed from STORM as new V06A HDF5 products are generated. TRMM Version 7 HDF4 products will continue to be available as well as the new HDF5 products at PPS by FTP (ftp://pps.gsfc.nasa.gov). The new TRMM HDF5 products can be found under the /gpmdata group as TRMM products are now considered part of GPM.

TRMM experienced extended data gaps due to the satellite altitude increase in 8/2001, the A to B hardware switch in 5-6/2009 and during the deorbit period in late 2014-2015.  For a listing of empty and partial granules in Version 7,  users can consult our PPS TRMM Anomalous Granule Table:

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

TRMM_TMI                                        1997-12-07 23:57:17                        2015-04-08 15:25:02

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/

We will include any new information in a future announcement.
