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 the first time. Markus Rex was honoured for his... view more... (2004-06-25)
European satellites provide new insight into ozone-depleting chemical species
Using data from the MIPAS and GOME-2 satellite instruments, scientists have for the first time detected important bromine species in the atmosphere. view more (2009-02-26)
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)
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)
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)
Global warming may delay recovery of stratospheric ozone
Increasing 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. view more (2009-02-05)
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 ultraviolet radiation as well as the impact of aircraft... view more... (2002-01-21)
Ozone layer depletion levelling off
By 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. view more (2009-09-22)
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 over Europe. "From 28-30 January, we observed a... view more... (2002-02-06)
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)
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)
Rocket launches may need regulation to prevent ozone depletion, says study
The global market for rocket launches may require more stringent regulation in order to prevent significant damage to Earth's stratospheric ozone layer in the decades to come, according to a new study by researchers in California and Colorado. view more (2009-04-01)
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)
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)
University of Toronto study shows climate change will lead to less ultraviolet radiation over northern high latitudes
Physicists at the University of Toronto have discovered that changes in the Earth's ozone layer due to climate change will reduce the amount of ultraviolet (UV) radiation in northern high latitude regions such as Siberia, Scandinavia and northern Canada. view more (2009-09-16)
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)
Climate change and atmospheric circulation will make for uneven ozone recovery
Earth's ozone layer should eventually recover from the unintended destruction brought on by the use of chlorofluorocarbons (CFCs) and similar ozone-depleting chemicals in the 20th century. view more (2009-04-13)
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)
