The GPM project has reprocessed all the original NRT IMERG data both EARLY and LATE to product version V04A. In addition, this reprocessing brought the IMERG dataset back to the beginning of the GPM mission in March 2014. The original NRT IMERG started its processing in March of 2015. Currently only the HDF5 products have been reprocessed to V04A. The TIFF/TFW versions will also be reprocessed but this will take a while longer. The V04 products are located in the directories early/YYYYMM and late/YYYYMM respectively. A subdirectory V03 has been created within those directories and the V03 data

Effective approximately 04:00 UTC, 9 May 2017 the near-realtime swath products (GMI, partner constellation, radar and combined) will be upgraded from V04 to V05. During the conversion the latency of near-realtime will be affected as all the new code and support files need to be modified to carry out this upgrade. We hope this will take no more than 2 hours but can not guarantee it might not be longer. We will start with the upgrade of radar products, followed as quickly as possible by GMI and then the partner constellation products. We are starting with the radar as this requires close

Tropical Cyclone Donna formed in the South Pacific Ocean northeast of Vanuatu On May 2, 2017 at 1800 UTC. A few hours earlier at 1521 UTC the GPM core observatory satellite passed above that area. GPM's Microwave Imager (GMI) instrument provided a clear view of the rainfall associated with the forming tropical cyclone. GMI revealed that an intense rain band was wrapping into the center of the forming tropical cyclone from the northern side. GMI data indicated that precipitation in one of these intense rain bands was falling at a rate of over 53 mm (~2 inches) per hour. GPM's Dual-Frequency

The Precipitation Processing System has begun the transition to GPM Version 5 products. The satellite observations made in April 2017 will be the last observations to be included in Version 4 of the GPM data products, with one exception. Starting with observations made in May 2017, PPS will generate Version 5 GPM data products, again with one exception. The exception in both cases is that the PPS Realtime system will continue to generate the Version 4 Early and Late IMERG data products. Version 4 data products have been removed from the STORM data ordering system ( https://storm.pps.eosdis

Tornadoes have accompanied severe weather over the United States almost daily during the past week. Severe storms spawned tornadoes from Texas and Oklahoma eastward through Mississippi. Upper Midwest states such Illinois, Indiana and Kentucky were also visited by tornadoes. Extreme rainfall caused deadly flooding in Missouri. More than a dozen people in the Midwest and South have been reported killed by tornadoes or flooding. The same weather system is spreading severe storms through East and Northeastern states today. NASA's Integrated Multi-satelliE Retrievals for GPM (IMERG) data were used
