Starting at 08:38 UTC PPS stopped getting data from the GPM Mission Operations Center. Data was resumed at 17:21 UTC. However, new GPS data was sent before older GPS data. The science data was sent out of order with the GPS data. This meant that about 125 mins of 1B and 1C GMI data had no geolocation and perhaps more after this had questionable geolocation. The same issues obviously also affected the radar and combined NRT which are just missing for the period between 8:30 UTC and 17:30 UTC. All of these issues impacted the early version of the IMERG data. The late product will also be

Typhoon Dolphin battered and drenched the islands of Guam and Rota as it passed over the channel between them last Saturday. Luckily for Guam, Dolphin's most powerful winds occurred after passing to the northwest of Guam. By May 16, 2015 Dolphin had winds estimated at 140 kts (161 mph) making it a category five super typhoon on the Saffir-Simpson hurricane wind scale. The GPM core observatory satellite flew above the weakening typhoon early this morning when winds had dropped to less than 100 kts (115 mph). GPM's Microwave Imager (GMI) found that Dolphin was dropping rain over the open waters

Typhoon Dolphin passed through the Northern Marianas today just to the north of Guam with sustained winds estimated at 95 knots (~109 mph) by the Joint Typhoon Warning Center. The center passed through the Rota Channel less than about 25 iles from the northern tip of Guam, close enough for the southern half of the eye wall to rake the northern part of the island with powerful winds. A wind gust of 106 mph was reported at Andersen Air Force Base located on the northeast corner of Guam. NASA's GPM Core observatory satellite captured this image of Dolphin just as the center was exiting the Rota

Typhoon Dolphin formed south of Pohnpei in the western Pacific Ocean on May 7, 2015. Dolphin's power has oscillated from a weak tropical depression to typhoon intensity over the past five days. Dolphin is now an intensifying typhoon headed westward. The GPM core observatory satellite flew over Dolphin on May 12, 2015 at 2301 UTC. At that time Dolphin's wind speeds were estimated at about 65 kts (75 mph). Rainfall collected by GPM's Microwave Imager (GMI) showed that rain was falling at a rate of over 47 mm (1.9 inches) per hour in a feeder band to the southeast of Dolphin's eye. Ku Band data

On May 9, 2015 at 1626 UTC ( 12:26 PM EDT) the GPM satellite flew over when Ana was making the change from subtropical storm to tropical storm. Convective storms near the inner-core region were warming the center of the storm with heat generated by condensation. GPM's Microwave Imager (GMI) measured rain falling at at rate of over 58.7 (2.31 inches) per hour in these convective storms near ANA's center. The lighter swath to the west of Ana's center shows the area viewed by GPM's Ku/Ka-band Dual-frequency Precipitation Radar (DPR). On Sunday morning (May 10, 2015) Tropical storm ANA dropped
