Stratospheric ozone chemistry plays an important role for atmospheric airflow patterns
Interactions between the stratospheric ozone chemistry and atmospheric air flow lead to significant changes of airflow patterns from the ground up to the stratosphere.   view more (2008-03-10)

AWI-Scientist Markus Rex Receives Dobson-Award
For his work on interactions between climate change and the ozone layer, Dr Markus Rex of the Alfred Wegener Institute for Polar and Marine Research (Research branch Potsdam) received the 'Dobson-Award' on May 31, 2004. The Quadrennial Ozone Symposium in Greece was chosen to present the award for... view more (2004-06-25)

Winds trigger increases in ozone destroying gases in upper stratosphere
A surprising new University of Colorado at Boulder study indicates winds circling high above the far Northern Hemisphere have a much greater impact on upper stratospheric ozone levels than scientists had thought.   view more (2006-09-29)

Inside the Ozone Layer
A new atmospheric model is able to quantify man-made versus naturally occurring damage to the stratosphere with an eye toward repairing the diminishing ozone layer that is located within the stratosphere.   view more (2006-02-24)

Volcanic aerosol clouds and gases lead to ozone destruction
Volcanic eruptions destroy ozone and create 'mini-ozone holes', according to two new studies by researchers at the Universities of Cambridge and Oxford.   view more (2006-11-09)

Ozone hole recovery may reshape southern hemisphere climate change
A full recovery of the stratospheric ozone hole could modify climate change in the Southern Hemisphere and even amplify Antarctic warming, according to scientists from the University of Colorado at Boulder, the National Oceanic and Atmospheric Administration and NASA.   view more (2008-04-25)

Ozone and UV over Europe: no sign of improvement
"The occurrence of ozone mini-holes over Europe increases and any ozone layer recovery could only become measurable around 2010 at the earliest" concludes an assessment report, released today, on European research in the stratosphere. The report concerns loss of ozone, increases in... view more (2002-01-21)

European low-ozone event reveals worrying trend
For several days last week, the protective ozone layer over Europe thinned considerably. Scientists monitoring ozone coverage using a rapid mapping technique based on data from the GOME (Global Ozone Monitoring Experiment) instrument aboard ESA`s ERS-2 satellite detected finger-like ozone thinning... view more (2002-02-06)

Computer models show major climate shift as a result of closing ozone hole
A new study led by Columbia University researchers has found that the closing of the ozone hole, which is projected to occur sometime in the second half of the 21st century, may significantly affect climate change in the Southern Hemisphere, and therefore, the global climate.   view more (2008-06-13)

Satellite instrument helps tackle mysteries of ozone-eating clouds
Polar stratospheric clouds have become the focus of many research projects in recent years due to the discovery of their role in ozone depletion, but essential aspects of these clouds remain a mystery.   view more (2006-04-11)

2008 ozone hole larger than last year
The 2008 ozone hole - a thinning in the ozone layer over Antarctica - is larger both in size and ozone loss than 2007 but is not as large as 2006.   view more (2008-10-08)

Rising surface ozone reduces plant growth and adds to global warming
Scientists from three leading UK research institutes have today released new findings that could have major implications for food production and global warming in the 21st century.   view more (2007-07-26)

2007 ozone hole 'smaller than usual'
The ozone hole over Antarctica has shrunk 30 percent as compared to last year's record size. According to measurements made by ESA's Envisat satellite, this year's ozone loss peaked at 27.7 million tonnes, compared to the 2006 record ozone loss of 40 million tonnes.   view more (2007-10-04)

Ozone recovering, but unlikely to stabilize at pre-1980 levels, says study
While Earth's ozone layer is slowly being replenished following an international 1987 agreement banning CFCs, the recovery is occurring in a changing atmosphere and is unlikely to stabilize at pre-1980 levels.   view more (2006-05-04)

New window into ancient ozone holes
British researchers have hit on a clever way to search for ancient ozone holes and their relationship to mass extinctions: measure the remains of ultraviolet-B absorbing pigments ancient plants left in their fossilized spores and pollen.   view more (2005-08-10)

NASA Study Links "Smog" to Arctic Warming
NASA scientists have found that a major form of global air pollution involved in summertime "smog" has also played a significant role in warming the Arctic.   view more (2006-03-15)

UCI scientists find chlorine may contribute to ozone formation
Standard methods of predicting air pollution don't take atmospheric chlorine into account, but the chemical could be responsible for 10 percent or more of daily ozone production in local air, research at UC Irvine has found.   view more (2006-06-14)

NASA and NOAA Announce Ozone Hole is a Double Record Breaker
NASA and National Oceanic and Atmospheric Administration (NOAA) scientists report this year's ozone hole in the polar region of the Southern Hemisphere has broken records for area and depth.   view more (2006-10-23)

Mountainous plateau creates ozone 'halo' around Tibet
Not only is the air around the world's highest mountains thin, but it's thick with ozone, says a new study from University of Toronto researchers.   view more (2005-12-08)

NASA's AURA satellite peers into Earth's ozone hole
NASA researchers, using data from the agency's AURA satellite, determined the seasonal ozone hole that developed over Antarctica this year is smaller than in previous years.   view more (2005-12-07)

New laboratory to study the oceans and air
Almost two-thirds of the planet is ocean and this has a major impact on our lives. Now the University of East Anglia (UEA) will be home to the world's first facility dedicated to the study of chemical ocean-air interactions which are important in regulating Earth's climate. Examples include ocean... view more (2003-11-21)

NASA Study Finds Clock Ticking Slower On Ozone Hole Recovery
The Antarctic ozone hole's recovery is running late. According to a new NASA study, the full return of the protective ozone over the South Pole will take nearly 20 years longer than scientists previously expected.   view more (2006-06-30)

NASA keeps eye on ozone layer amid Montreal Protocol's success
NASA scientists will join researchers from around the world to celebrate the 20th anniversary of the Montreal Protocol, an international treaty designed to reduce the hole in Earth's protective ozone layer.   view more (2007-09-14)

Grape expectations for healthier wine
A new technique that uses ozone to preserve grapes could help prevent allergies and boost healthy compounds at the same time, reports Jennifer Rohn in Chemistry & Industry, the magazine of the SCI.   view more (2007-02-12)

Geological reasons of ozone layer destruction
The modern science admits that the ozone concentration in the stratosphere is diminishing. This process has been fixing since the middle of 1980s. "The most popular hypothesis about technogenic freon that destroys the ozone layer is quite vulnerable", - said Dr. of geology Vladimir Sivorotkin who... view more (1999-10-19)
