Asia Sends Springtime Ozone Levels Soaring Over North America Boulder CO (SPX) Feb 02, 2010 
Springtime ozone levels above western North America are rising primarily due to air flowing eastward from the Pacific Ocean, a trend that is largest when the air originates in Asia.
Such increases in ozone could make it more difficult for the United States to meet Clean Air Act standards for ozone pollution at ground level, according to a new international study. Published online today in ... read moreWebsite For Astronomers To Report Unexplained Aerospace Phenomena 
Washington DC (SPX) Dec 22, 2009A website has been launched giving amateur and professional astronomers a formal mechanism for reporting any unexplained phenomena they observe when studying the night sky. Initiated within the framework of the International Year of Astronomy 2009 (IYA2009), the Unidentified Aerospace Phenomena (UAP) Observations Reporting Scheme aims to provide a global focus for sightings by astronomers ... more

Less Nitrogen Oxide In Tropical Weather Than Expected
Bonn, Germany (SPX) Dec 07, 2009Storms are more than just spectacular weather events; they also exercise considerable influence on atmospheric chemistry and Earth's climate. Lightning combines nitrogen and oxygen to form large amounts of nitrogen oxide. However, it is not known just how much nitrogen oxide is created by these events. Researchers from the German Aerospace Agency and the Institute of Atmospheric Physics ... more Fossil Fuel CO2 Emissions Up By 29 Percent Since 2000 
London, UK (SPX) Nov 18, 2009The strongest evidence yet that the rise in atmospheric CO2 emissions continues to outstrip the ability of the world's natural 'sinks' to absorb carbon is published in the journal Nature Geoscience. An international team of researchers under the umbrella of the Global Carbon Project reports that over the last 50 years the average fraction of global CO2 emissions that remained in the atmosp ... more NASA Conducts Airborne Science Aboard Zeppelin Airship 
Moffett Field CA (SPX) Oct 19, 2009NASA 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 ... more Missing 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 |

Iridescent Ice Clouds From Aircraft Wings
Bonn, Germany (SPX) Apr 03, 2009Not all condensation trails are the same. Scientists from the German Aerospace Center have, for the first time, been able to describe how condensation trails are created not only from the exhaust gas of jet engines but, under certain conditions, also by the wings of aeroplanes. It is unclear to what extent this new class of condensation trail influences climate change, as up until now it h ... more Australia issues warning on Hong Kong's dirty air 
Hong Kong (AFP) March 25, 2009Australia has issued a new health alert to travellers, warning that Hong Kong's bad air could aggravate some medical conditions. The updated advice on the Department of Foreign Affairs website said "levels of air pollution in Hong Kong may aggravate bronchial, sinus or asthma conditions". "People with existing heart or respiratory illnesses should reduce physical exertion and outdoor act ... more Rendezvous With HALO 
Bonn, Germany (SPX) Mar 06, 2009The pilots and scientists of the 31 research institutes who supported the construction of the Euro 62 million jet have waited a long time for this day. Many of DLR's employees are using their lunch break to watch the takeoff of the eagerly awaited aeroplane. While the technician on duty asks his colleagues to leave the apron, the film crew that has arrived for the airworthiness certificati ... more SKoreans buy air purifiers amid "yellow dust" warning 
Seoul (AFP) Feb 27, 2009South Koreans are stocking up on air purifiers following a forecast of especially severe "yellow dust" storms from China and Mongolia this spring, officials said Friday. Forecasters say the annual dust storms will be particularly bad this spring because north China and the deserts of Mongolia, where they originate, suffered the worst drought in 50 years. The temperature there is also two ... more |
