On May 10, 2017 rapidly dissipating tropical Cyclone Donna moved to the southeast of New Caledonia in the South Pacific. In addition to being the most powerful out-of-season tropical cyclone ever recorded in the southern hemisphere, Donna also dropped extreme amounts of rainfall along it's path. Donna spread heavy rainfall along it's path from northern Vanuatu through the Loyalty Islands east of New Caledonia. Over 250mm (~10 inches) of rainfall was reported in the islands of northern Vanuatu as Donna was moving through on May 5, 2017. This rainfall analysis was constructed using data from

The GPM core observatory satellite flew over intensifying tropical cyclone Ella in the South Pacific on May 10, 2017 at 2301 UTC. The satellite's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed bands of curved rainfall bands wrapping into the center of a well defined center of circulation. GPM's DPR measured rain falling at a rate of over 231 mm (9.1 inches) per hour in an intense feeder band on Ella's eastern side. This 3-D view of tropical cyclone Ella was produced using GPM radar reflectivity data (DPR Ku Band). DPR showed that the highest storm tops

The above window displays an interactive visualization of GPM data collected from Tropical Cyclone Donna on 5/7/17. Over the weekend tropical cyclone Donna dropped very heavy rain over Vanuatu as it moved toward the west of the islands. Donna had intensified and had maximum sustained winds of 115 kts (132 mph) on Monday morning. This made it the equivalent of a category four on the Saffir-Simpson hurricane wind scale. The GPM core observatory satellite had two excellent views of the intensifying tropical cyclone Donna on succeeding days. When GPM flew over Donna on May 6, 2017 at 0146 UTC the

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
