During the initial setup up for V04 IMERG, an error was made in the configuration for running the EARLY version of IMERG. This affected the V04A early data from Feb 5 - March 12, 2017. This error caused the early and the late products to be identical. Given that the LATE product is the more accurate product this might not be an issue for many users. However, users who need a consistent approach in the early data will need to download IMERG early Feb 5-March 12, 2017 again. On April 12, 2017 at about 16:55 UTC Feb 5-Feb 28, 2017 files have been rerun and are available from their usual location...

PPS received replacement GPM Ka/Ku L1B products from JAXA and will reprocess the affected data. If you have already obtained products with orbit #17356 from our archive or through a standing order, etc., please discard and use the replacement products. PPS has replaced the following GPM Ka/Ku L1B data: GPMCOR_KUR_1703190533_0705_017356_1BS_DUB_04A.h5 GPMCOR_KAR_1703190533_0705_017356_1BS_DAB_04A.h5 ------------------------------------- PPS will reprocess these affected downstream products shortly. 2A.GPM.Ka.V6-20160118.20170319-S053318-E070552.017356.V04A.HDF5 2A.GPM.Ku.V6-20160118.20170319...

On the afternoon of March 16, one of the TDRSS data relay satellites went into safe hold. This has reduced the relay satellites available for downloading the data from the GPM core satellite to the ground station at White Sands, NM. It means that times between download contacts have increased. No data is lost but data latency has been greatly affected for the GPM near-realtime core satellite products: GMI and DPR. We understand that this increase in latency will be the norm for the next couple of days. There are NO issues with the GPM core satellite or its sensors. Also there are NO issues...

The algorithm for the Integrated Multi-satellitE Retrievals for GPM (IMERG) Early and Late Runs has now been upgraded to Version 04. The transition to V04 began at 15 UTC on March 13 and both the early and the late products were back to their target latency by 01:00 UTC, March 14. The transition took longer than planned but the core IMERG version 04 products are now running automatically as the original V03. The product version is V04A and you will see this in the name of the IMERG HDF5 products. For IMERG late the V03 products have remained before February 05, 2017. For IMERG early V03...
