The Sixth International Ground Validation Workshop will be held November 5 -7 in Rome, Italy, at the headquarters of the National Research Council of Italy ( CNR), Institute of Atmospheric Sciences and Climate ( ISAC). The workshop is organized in coordination with NASA’s Precipitation Measurement Missions Science Program. The meeting will focus on activities related to the upcoming launch of the Global Precipitation Measurement mission's Core Observatory, including: Developing consensus plans for post-launch assessments of satellite algorithms/products using GV measurements Reviewing results

Typhoon Francisco was headed toward the islands of southern Japan when the TRMM satellite had a good view on October 22, 2013 at 0933 UTC. Francisco was weakening and had estimated winds of less than 75kts (~86 mph) with this TRMM pass. An analysis derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown overlaid on an enhanced infrared image from TRMM's Visible and InfraRed Scanner (VIRS). This analysis showed that the most intense rain was falling at a rate of over 75mm/hr (~3 inches) in a location well to the southwest of Francisco's center of circulation

A month ago hurricane Manuel caused caused landslides and extensive flooding along Mexico's Pacific Ocean coast. Recently formed hurricane Raymond is expected to cause heavy rainfall in nearly the same area. The TRMM satellite flew directly above hurricane Raymond on October 21, 2013 at 0111 UTC (October 20 at 6:11 PM PDT). TRMM Precipitation Radar (PR) data from that orbit shows that hurricane Raymond contained towering thunderstorms on the western side of the eye wall that were reaching to heights above 15km (~9.3 miles). TRMM PR also recorded precipitation in Raymonds eye wall that was

Super typhoon Francisco is headed toward Japan as the country is still recovering from typhoon Wipha. The TRMM satellite flew above the western Pacific and caught a good view of super typhoon Francisco on October 20, 2013 at 0947 UTC. A precipitation analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments found that rain was falling at the extreme rate of over 207 mm/hr (~8.1 inches) in an area of violent storms southwest of Francisco's eye. TRMM's Precipitation Radar (PR) discovered radar reflectivity values of over 53dBZ in heavy precipitation south of Francisco

The sixth super typhoon of 2013 called Francisco developed in the Western Pacific Ocean on October 16, 2013. The image on the left was made from data collected as the TRMM satellite passed over on October 18, 2013 at 1002 UTC when super typhoon Francisco was located west-northwest of Guam. A rainfall analysis that used data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown on the left overlaid on an enhanced infrared image from TRMM's Visible and InfraRed Scanner (VIRS). TRMM PR found that rain was falling at a rate of over 113 mm/hr (~4.5 inches) in powerful
