On 1 December 2017 sometime between 07:00 UTC and 12:00 UTC, PPS will begin installing V05B algorithms for the near realtime (NRT) IMERG dataset. If no problems arise, the installation should take approximately 4 hours. During this period IMERG products will be unavailable. While this is the first V05 IMERG available from NRT, we are making the data product version V05B so that both the early and the late product will be consistent with the version of the final product which is at V05B. To avoid unnecessary emails, PPS will not send out an email when the V05 installation is complete. Users

Starting the week of November 20, PPS will generate and release Version 05B of the GPM IMERG Final products. The Version 05A GPM IMERG Final products with data dates between March and October 2014 products are valid HDF5 science products. However, these products yield errors when opened with NetCDF4 utilities and library. To satisfy the requirements of the NetCDF4 users, PPS will release Version 05B GPM IMERG Final products starting next week. All the contents, data format, data server address and documents are unchanged. If you are a HDF5 user, you can keep using these Version 05A products or

Starting on Monday November 13, 2017, PPS will generate Version 05 GPM IMERG Final products. The V05 IMERG Final products will be available both in STORM: https://storm.pps.eosdis.nasa.gov/storm/ and on "arthurhou": ftp://arthurhou.pps.eosdis.nasa.gov/ NASA requires that science users register at: https://registration.pps.eosdis.nasa.gov/registration/ to access PPS data services. PPS will reprocess the V05 IMERG Final products back to data date March 12, 2014. All users are encouraged to retrieve the V05 IMERG Final products to ensure that they use the most recent products. The V04 IMERG

25 October 2017 At about 4:57 UTC on 9 October 2017 the NOAA-19 MHS precipitation estimates started displaying artifacts, which was eventually traced to the instrument going into safe mode without shutting down data delivery. Since this happened over the long Columbus Day weekend, it took until 01:47 UTC on 10 October 2017 to shut down the data stream, so the Early and Late IMERG have these (very obvious) artifacts for almost 24 hours. No reprocessing is planned. The sensor resumed operations at 17:31:08 UTC on 16 October 2017, but because the basis for the safe mode was unknown, GPM chose to

PPS received replacement GPM Ka L1B (20378) and Ka/Ku L1B (20379) products from JAXA and will reprocess the affected data including Level 2 and 3 data. If you have already obtained products with orbit# 20378-20379 from our archive or through a standing order, etc., please discard and use the replacement products.

With the completion of the TRMM era GPM constellation version 8 level 1 processing, PPS will start to process the TRMM era MHS, SSMIS, AMSR2 and ATMS version 8 level 2 and level 3 GPROF products on Monday October 16, 2017. Similar to the TRMM version 8 level 1 constellation 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 file naming convention: https://pps.gsfc.nasa.gov/Documents/FileNamingConventionForPrecipitatio… and the produced data will appear both in STORM
