The PPS (Precipitation Processing System) will be down Sunday September 18, 2016 -estimated time from 10:00am to 6:00pm EDT (14:00 - 22:00 UTC) for Special Unscheduled Maintenance. Please note: although it is unlikely, due to unforeseen events PPS systems might be down overnight and only be available starting Monday morning, September 19, 2016. During this time, all data transfers between PPS source and its consumer systems (GDAAC/DISC) as well as Science User services (FTP and STORM access) will be unavailable. You may e-mail “sysgods@mail.pps.eosdis.nasa.gov” if there are any urgent matters

Tropical storm Julia was recently downgraded to a tropical depression. The GPM core observatory satellite had an excellent view of tropical storm Julia on September 14, 2016 at 9:36 PM EDT ( September 15, 2016 0136 UTC). Julia was barely a tropical storm at that time with maximum sustained winds of about 40 mph ( 35 kts). Over the past few days Julia has dropped heavy rain along the Atlantic coastline from northeastern Florida to North Carolina. Some areas have received over 8 inches (203 inches) during the past few days. The GPM satellite measured Julia's rainfall and found that intense

FNMOC is behind in providing the SSMIS data used in IMERG. Therefore, the Early and possibly Late IMERG products will contain less satellite estimates and be of somewhat lesser quality. FNMOC stopped providing data around 00 UTC today (8 September 2016), meaning there has been no data available from the three operational SSMIS sensors to the TMPA-RT datasets. As a result, more lower-quality IR-based estimates are being used. In addition, if there are dropouts in the IR data, there is a higher probability that gaps will appear in the combined product, 3B42RT. We will update the situation when

Post Tropical Cyclone Hermine was still rotating in the Atlantic Ocean east of New Jersey when the the GPM core observatory satellite flew above on September 6, 2016 at 2:05 PM EDT ( 1806 UTC). Hermine's power was greatly dissipated from the hurricane that hit Florida on September 2, 2016. Hermine still had maximum sustained winds of about 58 mph (50 kts). Hermine was also still producing some light to moderate showers. Precipitation data shown here were derived from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments. Those data showed that rain was falling

Tropical Depression Nine was upgraded to Tropical Storm Hermine on Wednesday August 31, 2016 at 2 PM EDT (1800 UTC). The GPM core observatory satellite passed directly above newly designated tropical storm Hermine on August 31, 2016 at 4:06 PM EDT (20:06 UTC). Rainfall data derived from GPM's Microwave (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that precipitation intensity had increased and moved into western Florida. Rainfall measured by GPM's DPR had increased to a rate of over 9.9 inches (251 mm) per hour in very powerful storms in the Gulf Of Mexico northwest of
