Warnings have been posted in the extreme northeastern Philippines as Parma has powered up into a Super Typhoon, and its new forecast track takes it over the northeastern tip of the Philippines, and three NASA satellites are keeping tabs on it. Public storm warning signal 1 is in force in Camarines Norte & Sur and Catanduanes, the Philippines. Overnight, Parma's sustained winds increased to 149 mph (130 knots), just 7 mph shy of a Category 5 typhoon. Right now, Thursday, October 1 at 0900...

The latest tropical storm in the western Pacific formed on Sunday, and is poised to make landfall in mainland China on Tuesday, near typhoon strength (74 mph). Tropical Storm Koppu, the sixteenth tropical cyclone in the western Pacific Ocean, also deemed "16W," had sustained winds near 69 mph (60 knots) today, September 14. Koppu is expected to strengthen just a little more before it makes landfall in China. It was centered near 20.6 north and 114.6 east, about 130 nautical miles...

Typhoon Vamco is being as stubborn in its quest to live in the Pacific Ocean as Bill is in the Atlantic Ocean this week, and NASA satellite data confirmed that the large storm has a huge eye, about 45 miles in diameter! NASA's Aqua satellite flew over Typhoon Vamco early today, Monday, August 24, and infrared imagery from Aqua's Atmospheric Infrared Sounder (AIRS) instrument clearly showed Vamco's 45-mile in diameter eye. Around the huge eye, AIRS showed Vamco's cold high thunderstorm cloud...

Felicia is the storm that rules the Eastern Pacific Ocean this week, but Enrique refuses to give up. Felicia is a major hurricane with sustained winds near 140 mph, and Enrique is still hanging onto tropical storm status with 50 mph sustained winds. Both cyclones are close to each other and two NASA satellites captured them together.On August 6 at 5 a.m. EDT, powerful Felicia is still a category four hurricane on the Saffir-Simpson hurricane scale. She's far out to sea, about 1,480 miles...

Using radiation measurements obtained by the MetOp satellite, scientists have produced the first complete map of global ammonia emissions "“ a pollutant of key environmental concern. The map, based on observations throughout 2008, shows inaccuracies in current ammonia inventories and identifies new hotspots. Ammonia emissions contribute to a host of environmental problems, including soil acidification, reductions in biodiversity and the formation of atmospheric particulate matter,...

Twenty years ago, Brent Holben was part of a NASA team studying vegetation from space. In an unlikely career twist, his research morphed into the study of a critical, if overlooked, subplot in the story of climate change.From his office at NASA's Goddard Space Flight Center in Greenbelt, Md., Holben helps manage the world's largest network of ground-based sensors for aerosols -- tiny specks of solids and liquids that waft about in the atmosphere. These particles come from both human and...

WASHINGTON, May 28 /PRNewswire-USNewswire/ -- Researchers have conducted the first global analysis of the health and productivity of ocean plants using a unique signal detected by NASA's Aqua satellite. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) Ocean scientists can now remotely measure the amount of fluorescent red light emitted by phytoplankton and assess how efficiently these microscopic plants turn sunlight and nutrients into food through photosynthesis. Researchers...

NASA will hold a media teleconference on Thursday, May 28, at 1 p.m. EDT, to present the first-ever global views of the health of marine plant life. Using a new measure of the health of phytoplankton in the world's oceans made possible by data from NASA's Aqua satellite, scientists have discovered new regions where marine ecosystems are under stress. Worldwide, phytoplankton play a key role in the food chain of marine fisheries and the balance of carbon dioxide in the atmosphere. The new...

About half of the oil in the ocean bubbles up naturally from the seafloor, with Earth giving it up freely like it was of no value. Likewise, NASA satellites collect thousands of images and 1.5 terabytes of data every year, but some of it gets passed over because no one thinks there is a use for it. Scientists recently found black gold bubbling up from an otherwise undistinguished mass of ocean imagery. Chuanmin Hu, an optical oceanographer at the University of South Florida, St. Petersburg,...

A remotely piloted aircraft carrying a NASA sensor flew over much of California earlier last week, gathering information that will be used to help fight more than 300 wildfires burning within the state. Additional flights are planned for this week. The flights by NASA's unmanned Ikhana aircraft are using a sophisticated Autonomous Modular Scanner developed at NASA's Ames Research Center at Moffett Field, Calif. The flights are originating from NASA's Dryden Flight Research Center at Edwards...
