For V05 we produced a daily gridded text product for precipitation data from the core satellite and from the partner constellation imagers. We also produced a monthly rollup of these gridded text products. They were all designated with the product version V05A. If you downloaded these products, we regret to inform you that we found an error in the calculation of convection rate and frozen rate. While the mean precipitation rate values were correct in V05A, convective and frozen rates were erroneous. We have made the necessary changes to the code that produces these products. After extensive...
PPS received new GPM Ka/Ku L1B products from JAXA and reprocessed the affected data including Level 2 and 3 daily products from 2017-07-29 00:34:47 -> 2017-07-29 02:07:20. If you have obtained any of these files from our archive or through a Standing Order, etc., please discard these and use the replacement products.

One of the TDRS satellites which GPM uses for downloading data is currently in safehold. This means that all downloads scheduled for that satellite wiil obviously not be able to be met. This will increase the latency of all GPM NRT products. One missed pass has already occurred and led to increased latency. Several others will occur during the night and into tomorrow.
PPS has completed the production of the GIS-friendly TIF/TFW products created from the IMERG Early dataset. These products include running accumulations at 3hr and 1day. The Early TIF/TFW GIS-friendly products have been created back to the beginning of the mission: March 2014. They can be found on jsimpson server in the directories: /NRTPUB/imerg/gis/early/YYYY/MM Documentation for the TIF/TFW products is contained in the document README.GIS.pdf in /NRTPUB/imerg/gis.
