IMERG V06B GPM Retrospective Processing Completed

PPS has completed the retrospective processing of IMERG NRT early and late products to version V06B. All GPM NRT IMERG is available at version V06B from June 2014 through the current IMERG data. The GPM NRT IMERG from March 2014 through May 2014 will be available once the TRMM era (2000-2014) retrospective processing is completed. THe V06B data is the default product (early and late) available on the jsimpson.pps.eosdis.nasa.gov NRT file server. Please contact us for any questions.

TRMM era IMERG Completed & End of FTP at PPS

IMERG is now available back to June 2000 of the TRMM era. Both the 'early' and the 'late' products have been retrospectively processed. These products are available in the same location on the jsimpson.pps.eosdis.nasa.gov FTP server as the current GPM IMERG products: /NRTPUB/imerg/early/YYYYMM and /NRTPUB/imerg/late/YYYYMM. We are in the process of retrospectively processing the GIS-friendly versions and accumulations of these IMERG products. This is likely to be completed by the end of September 2019. **IMPORTANT** A very important item is that we have been directed to eliminate ftp to all

TMPA End of Production

The combined TRMM and GPM-era (June 2000 – present) IMERG V06B products are now available. This includes the Final product, as well as the retrospectively reprocessed Early and Late products. These products are staged in the standard locations. If you have any questions regarding accessibility please contact us. As the long-record IMERG products are now available, the TMPA and TMPA-RT products have a planned end date of December 31, 2019. Users should transition to IMERG during this period. We are hopeful we can extend the IMERG record back to January 1998 in the near future. As always, we are

IR Anomalies in Early and Late IMERG

Beginning with August 19, 2019 at 13:00 UTC, noise in the form of random horizontal lines over the Eastern Pacific began appearing, with most of the problems appearing each following day in the 12:00, 12:30, and 13:00 half-hours, with at least one instance of 13:30. This was traced to noise in the GOES-W Tb’s (as the result of the faulty sensor cooling system), which made it past the filtering at CPC, where the Merged Global 4-km IR dataset is assembled. The Early and Late datasets contain these errors, which will be dealt with in the Final computation.

MHS NOAA-19 Data Processing Stop (PPS Will Halt NOAA-19 1C and GPROF Data)

PPS will halt the NOAA-19 L1C and GPROF products for the time being due to problems with the input received. Indications are that the NOAA-19 MHS channel 2 has failed. The input data (MSPPS_ORB) used for producing the NOAA-19 MHS L1C product is flagging all the Ta as missing, and as a result the L1C and GPROF products for NOAA-19 have ceased. We will inform you when and if we have any new details or announcements. Thank you for your attention and patience during this time.
Using the IMERG Long-term Precipitation Data for Applications
A long precipitation data set like the new GPM IMERG V06 product is valuable for many applications and for decision-making. Accurate and reliable precipitation records are not only crucial to understanding trends and variability but also for water management resources and food security, ecological management, and weather, climate and hydrological forecasting. Here we present a few highlights showcasing how GPM IMERG is helping a variety of end users make decisions that will benefit society for years to come.

IMERG Real Time IR Outage

For the period 03Z August 21 to 16Z August 22, the IMERG real time system experienced an outage of CPC 4-km IR data. Despite the outage, IMERG EARLY and LATE products continued to be produced but users should be aware that the quality of these products during this period may be suspect and should be used judiciously. Furthermore, the products for the first few hours after the outage are less than optimal due to IMERG restart but should be acceptable for most users. Detailed Impacts: (1) The precipitation propagation vectors for the period slowly degraded after 03Z August 21 due to the missing
