Scientists create small ozone sensor Freiburg, Germany (UPI) Jan 27, 2009 
German scientists say they've developed a highly sensitive, miniaturized mobile ozone sensor that can operate in the air or water.
The researchers at the Fraunhofer Institute for Applied Solid State Physics note ozone is a powerful oxidizing agent and can cause a wide range of symptoms in humans, including headaches, coughing and even deterioration in lung function.

West Lafayette IN (SPX) Dec 08, 2009There is more to the snowflake than its ability to delight schoolchildren and snarl traffic. The structure of the frosty flakes also fascinate ice chemists like Purdue University's Travis Knepp, a doctoral candidate in analytical chemistry who studies the basics of snowflake structure to gain more insight into the dynamics of ground-level, or "tropospheric," ozone depletion in the Arctic. ... more

Ozone Layer Depletion Levelling Off
Paris, France (ESA) Sep 22, 2009By merging more than a decade of atmospheric data from European satellites, scientists have compiled a homogeneous long-term ozone record that allows them to monitor total ozone trends on a global scale - and the findings look promising. Scientists merged monthly total ozone data derived from the vertically downward-looking measurements of the GOME instrument on ESA's ERS-2 satellite ... more NASA Satellite Data Show Progress Of 2009 Antarctic Ozone Hole
Greenbelt MD (SPX) Sep 18, 2009The annual ozone hole has started developing over the South Pole, and it appears that it will be comparable to ozone depletions over the past decade. This composite image from September 10 depicts ozone concentrations in Dobson units, with purple and blues depicting severe deficits of ozone. "We have observed the ozone hole again in 2009, and it appears to be pretty average so far," said ... more Ozone hole smaller in 2009 than 2008: WMO
Geneva (AFP) Sept 16, 2009The World Meteorological Organisation said Wednesday that the ozone hole is expected to be smaller in 2009 than a year ago. "The meteorological conditions observed so far could indicate that the 2009 ozone hole will be smaller than those of 2006 and 2008 and close to that of 2007," said the UN agency in a statement. The hole in the layer over the Antarctic was discovered in the 1980s. It ... more Ozone: Climate change boosts ultraviolet risk for high latitudes 
Paris (AFP) Sept 6, 2009Climate change will disrupt Earth's precious ozone layer, boosting ultraviolet (UV) radiation in the deep southern hemisphere and reducing UV in far northern latitudes, a study warned on Sunday. By century's end, UV levels in Antarctica could rise by up to 20 percent at seasonal peaks while average exposure in northern Scandinavia, Siberia and northern Canada could fall by almost a tenth. ... more |
