Tropical Storm Talim's Heavy Rainfall Over Taiwan

JacobAdmin Thu, 06/21/2012
Tropical storm Talim has produced torrential rainfall over southern Taiwan as it pumped warm moist air from the South China Sea over mountainous terrain. The TRMM satellite flew over tropical storm Talim in the Taiwan Strait on 20 June 2012 at 0140 UTC. TRMM Precipitation Radar (PR) data from this orbit shows that tropical storm Talim was dropping rainfall at a rate of almost 50mm/hr over Taiwan. TRMM data captured with that orbit shows that the most intense rainfall of over 50mm/hr (~2 inches) was located over the Strait Of Taiwan. Flash flooding and landslides are probable in southern Taiwan

Guchol's Rainfall Drenching Japan

Guchol's Rainfall Drenching Japan
The TRMM satellite passed above weakening typhoon Guchol on 18 June 2012 at 2322 UTC as it moved toward Japan's main island of Honshu. Guchol's past and predicted locations are shown overlaid in white. A precipitation analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments show that the Japanese islands of Kyushu and Shikoku were getting rainfall from Guchol at the time of that orbit. Guchol was shown by TRMM to be enhancing rainfall in parts of Japan over 500 km (~310.7 miles) from the typhoon's center.

Hurricane Carlotta Moves Toward Mexican Coast

TRMM image of hurricane Carlotta
The TRMM satellite flew over hurricane Carlotta again on Friday June 15, 2012 at 1018 UTC. TRMM's Microwave Imager (TMI) showed that Carlotta was much better organized and revealed a developing eye. Heavy rainfall in bands spiraling into the center of Carlotta are shown by TRMM's Precipitation Radar (PR). Past positions and the National Hurricane Center's forecast positions are shown overlaid in white. Carlotta is forecast to become a category two hurricane tomorrow with sustained wind speeds increasing to 85kts (~98 mph) as it nears the Mexican coast.

Intensifying Typhoon Guchol Viewed By TRMM

TRMM radar image of Guchol
Typhoon Guchol in the western Pacific Ocean is becoming increasingly more powerful and was seen by the TRMM satellite on Friday June 15, 2012 at 0443 UTC. The center of the intensifying typhoon was covered very well by TRMM's Precipitation Radar (PR) data. TRMM PR showed that very heavy rainfall was occurring in the eastern side of Guchol's eye wall. This 3-D image (looking toward the east) from TRMM PR data reveals that towering storms in the eastern side of Guchol's eye were reaching the amazing height of almost 17km (~10.56 miles). Intense rainfall in Guchol's eye wall was returning values

Tropical Storm Guchol Slowly Strengthens

TRMM image of Guchol
The tropical depression (05W) that became tropical storm Guchol yesterday formed southeast of Guam on June 11, 2012. TRMM had a fairly good daytime look at Guchol on June 13, 2012 at 0500 UTC. TRMM's Microwave Imager (TMI) data revealed that Guchol contained a large area of moderate to heavy rainfall. Guchol is expected to continue moving toward the northwest, slowly intensify and reach minimal typhoon strength on June 14, 2012.

TRMM Sees Flooding Rainfall Along Gulf

TRMM image of heavy rainfall over the U.S. South
The states along the coast of the Gulf of Mexico experienced very heavy rainfall on Saturday June 9,2012 and Sunday June 10, 2012. The images above use TRMM satellite data collected when it flew over on Sunday June 10, 2012. Unusually heavy rainfall was occurring in states near the Gulf coast. Due to the path of TRMM's orbits it had good coverage with more than one orbit. The first orbit occurred at 1501 UTC (11:01 AM EDT). The second image shows a combination of more than one orbit with the later data being collected at about 1817 UTC (2:17 PM EDT). TRMM rainfall analyses from these orbits
Global Precipitation Measurement Constellation JacobAdmin Fri, 06/08/2012

Nine U.S. and international satellites will soon be united by the Global Precipitation Measurement (GPM) mission, a partnership co-led by NASA and the Japan Aerospace Exploration Agency (JAXA). NASA and JAXA will provide the GPM Core satellite to serve as a reference for precipitation measurements made by this constellation of satellites, which will be combined into a single global dataset continually refreshed every three hours.
 

Late Season Tropical Storm Kuena Forms

TRMM image of Kuena
A tropical storm called Kuena formed in the southwest Indian Ocean east of Madagascar on June 6, 2012. This is a little unusual because the tropical cyclone season in that area normally ends on May 15. The TRMM satellite had an excellent view of Kuena when it flew directly above the newly formed storm on June 6, 2012 at 1607 UTC. A rainfall analysis that used data 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) instrument. This analysis shows that heavy convective storms

Successful Electrical Integration of GPM’s Two Instruments

The electrical integration of the Global Precipitation Measurement Microwave Imager (GMI) instrument onto the GPM Core Observatory was successfully completed in April 2012. Ball Aerospace and Technologies Corp. Boulder, Colo. built the GMI, which arrived at NASA's Goddard Space Flight Center in Greenbelt, Md. in early March and after post shipment processing it was handed over to NASA. The GMI is one of the key instruments for the GPM Core Observatory. This instrument is a passive radiometer with 13 channels covering frequencies from 10 to 183 GHz. In May, 2012, the Dual-frequency
