The GPM core observatory satellite flew over forming tropical depression 08E on July 27, 2015 at 1931 UTC ( 12:31 PM PDT). Rainfall was measured by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) falling at a rate of 50 mm (almost 2 inches) per hour in storms near the center of the tropical depression. The National Hurricane Center (NHC) predicts that TD08E will not intensify very much because northwesterly vertical wind shear is retarding development. GPM's DPR instrument scan (shown in lighter shades) viewed an area east of the center of the developing tropical

Typhoon Halola is predicted by the Joint Typhoon Warning Center (JTWC) to weaken to tropical storm intensity over the next couple days while passing to the north of Okinawa, Japan. Recent predictions of Halola's track are shown overlaid in red. The GPM core observatory's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) measured rainfall as it flew directly over typhoon Halola in the western Pacific Ocean on July 23, 2015 at 1414 UTC. A simulated 3-D flyby around typhoon Halola was made from GPM Radar data (Ku Band). This animation shows that that Halola's eye wall was

Satellite technology has the ability to see things we could never imagine, like how hard the rain is falling in storms, and how high cloud tops stretch into the atmosphere. The Global Precipitation Measurement (GPM) core observatory satellite does both of those things and has been providing that information each time it passes over Typhoon Halola in the Northwestern Pacific Ocean. The GPM core observatory is a joint effort between NASA and the Japan Aerospace Exploration Agency. GPM saw Halola when it was strengthening from a tropical storm into a typhoon. GPM flew over Tropical Storm Halola

Moisture pumping into southern California and the Desert Southwest from the remnants of hurricane Dolores has caused record July rainfall. This rainfall may provide some drought relief to the state of California that has been in the grip of exceptional drought conditions. Heavy flooding caused an interstate 10 bridge collapse on Sunday July 19, 2015 forcing closure of this main roadway between Southern California and Phoenix, Arizona. Data from NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) were used to estimate the extreme amount of rain that fell during the past week in that

Typhoon Nangka was a super typhoon with winds of 135 kts (155 mph) over the open waters of the Pacific Ocean last week. Nangka is predicted by the Joint Typhoon Warning Center (JTWC) to have weakened to barely typhoon intensity with winds of less than 65 kts ( 75 mph) before hitting Japan on July 16, 2015. The GPM core observatory satellite passed above early in the life of the typhoon on July 6, 2015 when Nangka was east-southeast of Guam. At that time Nangka had formed a nearly perfectly circular eye that contained powerful storms reaching to altitudes of close to 17km (10.5 miles). GPM flew
