GPM Scans Tropical Storm Nadine

GPM Scans Tropical Storm Nadine
Tropical Depression fifteen was located southwest of the Cabo Verde Islands when it became tropical storm Nadine early on October 9, 2018. The GPM core observatory collected significant information about Nadine when it scanned the tropical storm's center of circulation on October 10, 2018 at 3:01 AM EDT (0701 UTC). Nadine was a small tropical storm but GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) data revealed that extreme rainfall was occurring in areas around the center of the tropical cyclone. GPM's radar (DPR Ku Band) measurements indicated that rain was

GPM's GMI Measures Weakening Kong-Rey's Rainfall

GPM's GMI Measures Weakening Kong-Rey's Rainfall
The GPM core observatory passed above tropical storm Kong-Rey on October 5, 2018 at 0846 UTC. Kong-Rey was a powerful category five typhoon just a few days ago but increased vertical wind shear and cooler sea surface temperatures have caused the tropical cyclone to weaken dramatically. Tropical storm Kong-Rey had maximum sustained winds of about 55 kts (63 mph) when it was scanned by the satellite. GPM's Microwave Imager (GMI) data were used to gauge the intensity of precipitation around Kong-Rey's center of circulation. Energy observed through clouds by GMI's microwave channels was used to

Dive Into a 360-View of Hurricane Maria

Dive Into a 360-View of Hurricane Maria
Thursday, October 4, 2018
Two days before Hurricane Maria devastated Puerto Rico, the NASA/JAXA Global Precipitation Measurement Core Observatory satellite captured a 3D view of the 2017 storm. At the time Maria was a category 1 hurricane. The 3-D view reveals the processes inside the hurricane that would fuel the storm’s intensification to a category 5 storm within 24 hours. For the first time in 360 degrees, this data visualization takes you inside the hurricane. The precipitation satellite has an advanced radar that measures both liquid and frozen water. The brightly colored dots show areas of rainfall, where green...

GPM Examines Upgraded Hurricane Leslie

GPM Examines Upgraded Hurricane Leslie
The GPM core observatory satellite passed above hurricane Leslie on October 3, 2018 at 7:33 AM EDT (1133 UTC). Leslie had just been upgraded to a hurricane by the National Hurricane Center (NHC). GPM's Microwave Imager (GMI) instrument collected data that revealed light to moderate convective rainfall in Leslie's clearly evident eye wall. Very little precipitation was shown by GPM in the center of the hurricane's nearly circular eye. Algorithms developed by NASA's Precipitation Measurement Missions (PMM) science team indicated that rain was falling at over 1.8 inches (45.7 mm) per hour within

GPM Sees Walaka Becoming A Powerful Hurricane

GPM Sees Walaka Becoming A Powerful Hurricane
The GPM core observatory recently had a couple good looks at tropical storm Walaka as it was intensifying into a powerful hurricane. GPM passed directly over tropical storm Walaka when it was located south of the Hawaiian islands on September 30, 2018 at 8:38 AM HST (1838 UTC). Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that Walaka was well organized and very close to hurricane intensity. GPM's Radar (DPR Ku Band) data revealed intense convective storms in a large feeder band that was wrapping around the tropical storm's

Go To Class

GPM flying over Earth with a data swath visualized.
Friday, September 28, 2018
We Want You to Go to Class! Our students desperately need to have some face to face time with scientists and engineers who are doing amazing things to make their world a better place. That means you guys! From time to time, you may be invited to give a presentation on your work to kids in some context- and we want to make it easier for you. You might even reach out yourself to your local school and offer to come in and give a talk. Having been a classroom teacher across all grade levels by the time I finished my illustrious career, I know personally the joy of having real STEM professionals...

GPM Views Cat. 2 Typhoon Trami Moving Towards Japan

GPM Views Cat. 2 Typhoon Trami Moving Towards Japan
View fullscreen in STORM Event Viewer Once a Category 5 Super Typhoon, Trami has become rooted in place due to a lack of steering flow. This has caused the storm to deplete the warm waters beneath it and it has since weakened to a Category 2 with maximum winds of 90 knots. It maintains a broad eye and once it begins moving again, is likely to reintensify at least somewhat as it zooms northeastward over the Ryukyu Islands and into the southern coast of Japan. Wind impacts are likely to be exacerbated by its forward speed and current forecasts expect it to have widespread impacts in a region

GPM View Hurricane Rosa in the Eastern Pacific

GPM View Hurricane Rosa in the Eastern Pacific
The GMI overflight here shows a clear center of circulation with much of the intense convection on the south side of Hurricane Rosa, a Category 1 storm with winds of 75 knots. It is expected to continue intensifying over the next couple days before it runs into strong shear and cooler waters off the Baja California coast. Forecasts suggest it will make landfall in Northern Baja as a tropical storm, with its primary impacts being heavy rainfall and flash flooding over the Desert Southwest.

Super Typhoon Trami's Rainfall Examined By GPM

Super Typhoon Trami's Rainfall Examined By GPM
The GPM core observatory satellite probed super typhoon TRAMI when it traveled above the northwestern Pacific Ocean on September 24, 2018 at 1203 UTC. At that time TRAMI had maximum sustained winds estimated at 130 kts (150 mph). This image shows rainfall measurements that were made using data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments. GPM's GMI showed the locations of extremely heavy rainfall in the super typhoon's well defined circular eye. GPM's radar (DPR Ku Band) coverage was limited because it's swath only included storms on the
