redOrbit Staff & Wire Reports - Your Universe Online NASA has announced plans to send an unmanned, remotely-controlled research vehicle into the upper atmosphere in order to find out what impact climate change is having on our planet. The program, which has been christened the Airborne Tropical Tropopause Experiment (ATTREX), will utilize instruments on board a long-range Global Hawk aircraft to collect measurements above the tropical Pacific Ocean, the US space agency explained....

Thousands Of Microorganisms Make Their Way To West Coast Riding Plumes Across The Pacific
2012-12-18 10:48:12

University of Washington A surprising number of microorganisms — 99 percent more kinds than had been reported in findings published just four months ago — are leaping the biggest gap on the planet. Hitching rides in the upper troposphere, they´re making their way from Asia across the Pacific Ocean and landing in North America. For the first time researchers have been able to gather enough biomass in the form of DNA to apply molecular methods to samples from two large...

Deep Ocean Currents Affected By Atmosphere

Brett Smith for redOrbit.com - Your Universe Online Atmospheric researchers at the University of Utah have uncovered a Rube Goldberg-like mechanism that begins in the polar stratosphere and drives global weather patterns through a chain of interactions, according to a new report. "It is not new that the stratosphere impacts the troposphere," said University of Utah professor Thomas Reichler, senior author of the report published in the journal Nature Geoscience. "It also is not new...

WASHINGTON, May 9, 2012 /PRNewswire-USNewswire/ -- NASA researchers have flown off on a campaign that is taking them into the heart of thunderstorm country. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO ) The Deep Convective Clouds and Chemistry (DC3) field campaign is using an airport in Salina, Kan., as a base to explore the impact of large thunderstorms on the concentration of ozone and other substances in the upper troposphere. The campaign is being led by...

U.S. and British meteorologists said on Monday that not only is Earth's surface warming, but the troposphere is heating up also. The scientists found that warming in this key atmospheric layer was occurring, just as many researchers expected as more greenhouse gases build up and trap heat close to the Earth. This study put to rest a controversy that began 20 years ago when a 1990 scientific report raised questions about whether the troposphere was warming, even as Earth's surface...

Spanish researchers have measured CO2 levels for the past three years in the troposphere (lower atmosphere) over a sparsely inhabited rural area near Valladolid. The results, which are the first of their kind in the Iberian Peninsula, show that the levels rose "significantly" between 2002 and 2005. Over recent years, physicists and meteorologists have been trying to find out about carbon dioxide (CO2) levels, and how these have evolved in the troposphere over various urban and rural areas...

U.S. and Swiss scientists say unusual atmospheric circulation might have caused the 1930s Dust Bowl and could also be responsible for other droughts. The researchers from the Institute for Atmospheric and Climate Science in Zurich, Switzerland; the Observatory and World Radiation Center in Davos, Switzerland, and the U.S. National Climatic Data Center in Asheville, N.C., said they used historical upper air data, reconstructions and model simulations to analyze atmospheric circulation during...

Aircraft capable of flying 20 km above the surface of the Earth are being used to test instruments that could be carried on satellites to improve our understanding of how atmospheric chemistry and climate are linked. These types of high-altitude experiments support the candidate Earth Explorer PREMIER mission. PREMIER (PRocess Exploration through Measurements of Infrared and millimeter-wave Emitted Radiation) is one of the six candidate Earth Explorer missions that have just completed...
