NASA Conducts Airborne Science Aboard Zeppelin Airship Moffett Field CA (SPX) Oct 19, 2009 
NASA launched its first airborne science mission this week featuring a 246-foot-long Zeppelin NT airship equipped with two imaging instruments to learn more about environmental conditions in the San Francisco Bay Area. Scientists from NASA Ames Research Center's Earth Science Division are collaborating with Airship Ventures Inc., Moffett Field, Calif., to conduct experiments using the ... read moreMissing Link To Cloud Formation Found 
Copenhagen, Denmark (SPX) Aug 19, 2009The discovery of an unknown hitherto chemical compound in the atmosphere may help to explain how and when clouds are formed. The discovery of the so called dihydroxyepoxides (an aerosol-precursor), is reported in this week's issue of Science by a team comprising of researchers from the California Institute of Technology (Caltech) and the University of Copenhagen (UoC). Professor Henrik ... more

Aura Marks Five Years Of Sky-High Atmosphere Research
Pasadena CA (JPL) Aug 05, 2009Imagine Earth without an atmosphere - without clouds, wind or air. Earth's atmosphere protects, transports, and reacts to life on Earth. Without our ozone layer, the surface of Earth would be subject to harsh radiation coming from the sun. Without good quality air, public health and ecosystems suffer. And changes in the makeup of the atmosphere - such as to carbon dioxide, methane, nitrous oxide ... more Hong Kong proposes new air quality targets 
Hong Kong (AFP) July 23, 2009Hong Kong on Thursday laid out a series of proposals to tackle the city's poor air quality, but the move drew criticism from environmental groups who said new targets did not go far enough. Environment Secretary Edward Yau unveiled the targets to reduce pollutants like sulphur dioxide, nitrogen dioxide and particulates. If implemented, they would be the first new air quality targets in Hong ... more Massive dust storm in China circled the world in 13 days: study 
Paris (AFP) July 20, 2009A wind storm that ripped across western China's Taklimakan desert kicked up hundreds of thousands of tonnes of dust that high-altitude winds then carried around the world in less than two weeks, a study says. On May 8-9, 2007 winds reaching up to 36 kilometers (22.5 miles) per hour blew an estimated 800,000 tonnes of dust into the air, according to satellite imaging and computer models. ... more Referencing The Climatic Impact Of Desert Dust 
Granada, Spain (SPX) Jun 05, 2009In the context of the climatic change of the planet, those research works that throw light on global warming are of great interest. That is the case of the studies on atmospheric aerosol, a suspension of solid or liquid particles on a gaseous environment that can contribute to the warming or cooling of the atmosphere. Juan Luis Guerrero Rascado developed his doctoral thesis "Lidar ... more |

More Reasons To Hate Humidity
College Station TX (SPX) Feb 25, 2009Here's yet another reason to hate humidity: it expands global warming, says a Texas A and M University professor. Andrew Dessler, a professor in the Department of Atmospheric Sciences who specializes in research on climate, says that warming due to increases in greenhouse gases will lead to higher humidity in the atmosphere. And because water vapor itself is a greenhouse gas, this ... more Scientist Models The Mysterious Travels Of Greenhouse Gas 
Chicago IL (SPX) Feb 19, 2009The global travel logs of greenhouse gases are based on atmospheric sampling locations sprinkled over the Earth and short towers that measure the uptake or release of carbon from a small patch of forest. But those measurements don't agree with current computer models of how plants and soils behave. A University of Michigan researcher is developing a unique way to reconcile these crucial ... more Global Warming May Delay Recovery Of Stratospheric Ozone 
Baltimore MD (SPX) Feb 12, 2009Increasing greenhouse gases could delay, or even postpone indefinitely the recovery of stratospheric ozone in some regions of the Earth, a new study suggests. This change might take a toll on public health. Darryn W. Waugh, an atmospheric scientist at Johns Hopkins University in Baltimore, and his colleagues report that climate change could provoke variations in the circulation of air in ... more Science In The Stratosphere 
Dallas TX (SPX) Jan 28, 2009A young woman in a sleek red unitard flits through space just above the earth. Behind her trail a shock of orange hair and a pair of flowing nets as she patrols the upper atmosphere for stray dogs. This is CINDI, the android hero of a short comic book distributed by UTD's Hanson Center for Space Sciences to introduce elementary and middle school students to the basic science of the upper a ... more |
