IMERG Early Run Example January 24th, 2020

Data News

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.
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...
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 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...
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 NRT file server. Please contact us for any questions.
On 16 June 2019 at 22 UTC several hours of missing IR data and subsequent handling of this outage caused IMERG early and late products to be produced without IR data since that date/time. To ensure consistent early and late IMERG products it was decided to retroprocess these IMERG early and late products. All early and late IMERG products from 16 June 2019 at 22:00 UTC through June 19 were retroprocessed. You may wish to download the revised products from 16 June 2019 22:00 UTC onword. IMERG early and late are being produced again at their required latency: a. early: approx 4 hours from data collection b. late: approx 14 hours from data collection We are sorry for the extended unavailability of the products.
