Let it snow contest banner
Tuesday, March 5, 2013
The Global Precipitation Measurement mission is happy to announce the top ten winners of the "Let It Snow" photo competition. Thank you to everyone who submitted their best pictures of winter. From January 7th through February 4th 2013, over 1,000 photos were submitted via Flickr and Instagram (see the Flickr submissions here). We loved all of your entries and thoroughly appreciate your participation. We'll be sending the winning submitters GPM posters, lithographs, pins, and NASA and GPM stickers. Stay tuned and follow GPM for information about future events and contests, including our newest activity The GPM Anime Challenge, going on NOW until April 30th. Learn More About GPM

Tropical Cyclone Rusty's Flooding Rainfall

Tropical Cyclone Rusty's Flooding Rainfall
In addition to high winds tropical cyclone Rusty's heavy rainfall caused flooding in north-western Australia. The TRMM satellite's main purpose is the accurate measurement of tropical rainfall around the globe. TRMM is also used to calibrate rainfall estimates from other satellites. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (TMPA) at the NASA Goddard Space Flight Center provides estimates of rainfall over the global Tropics. TMPA rainfall totals in association with tropical cyclone Rusty are shown for the period from February 21-28, 2013. Rusty's approximate 0000Z

Tropical Cyclone Rusty Moves Into Australia

Tropical Cyclone Rusty Moves Into Australia
On February 27, 2013 at 0559 UTC The TRMM satellite again saw tropical cyclone Rusty moving toward Australia's coastline north-west of Hedland. A rainfall analysis derived from TRMM's Microwave Imager (TMI) data is shown overlaid on a visible/infrared image from the TRMM Visible and InfraRed Scanner (VIRS). Rusty's eye, surrounded by light to moderate rainfall, was revealed by TRMM's TMI data to be located very near the coastline.

Tropical Cyclone Batters and Drenches Samoan Islands

The TRMM satellite had an excellent view of tropical cyclone Evan on December 12, 2012 at 1704 UTC when it was battering the Samoan Islands with hurricane force winds. Evan is predicted by the Joint Typhoon Warning Center (JTWC) to intensify and have winds of 130kts (~150 mph) while remaining close to the islands. This wind speed would make it a strong Category 3 storm on the Saffir-Simpson Scale. A storm surge of 4.5 meters (14 feet) was reported along the Samoan coast. Evan's rainfall was analyzed using TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data. This analysis shows that

Category 3 Tropical Cyclone Evan

Category 3 Tropical Cyclone Evan
Intensifying tropical cyclone Evan devastated the Samoan Islands when it passed over the islands on December 13, 2012. The TRMM satellite flew directly above Evan today (December 14, 2012) at 0659 UTC when the tropical cyclone was a category 3 on the Saffir-Simpson scale with winds of 100kts (115 mph). TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data were used in the rainfall analysis on the first image. TRMM's Precipitation Radar (PR) showed that very intense storms in Evan's eye wall were dropping rain at a rate of up to 147mm/hr (~5.8 inches). The strongest radar reflectivity

Freda Brings Heavy Rains to New Caledonia

Freda Brings Heavy Rains to New Caledonia
After forming just south of the Solomon Islands on the evening of December 28th (local time), Cyclone Freda moved southward and intensified, becoming a strong Category 3 cyclone on the 30th. As the storm continued to move south, it weakened significantly and approached the island of New Caledonia on the 2nd of January 2013 as a tropical storm. TRMM captured this image of Freda at 07:16 UTC (6:16 pm local time) 2 January 2013. The image shows an instantaneous snap shot of the rain intensities within Freda. Rain intensities in the center of the swath are from the TRMM Precipitation Radar (PR)

Extreme Rainfall Causes Flooding Over Eastern Australia

Extreme Rainfall Causes Flooding Over Eastern Australia
A large area of low pressure from the remnants of tropical storm Oswald has caused additional extremely heavy rainfall as it moved southward over eastern Australia. This deluge has caused flooding in areas from the Cape York Peninsula to the Queensland state capital, Brisbane. At least four deaths have been attributed to the high winds and flooding associated with this low pressure system. This image shows a TRMM calibrated Multi-satellite Precipitation Analysis (MPA) for the period from January 21-28, 2013. This analysis shows that tropical cyclone Oswald dumped over 600mm (~23.6 inches) of
