Strong ozone depletion expected over Arctic in the coming weeks

Strong ozone depletion expected over Arctic in the coming weeks

POLSTRAC campaign initiated by the Karlsruhe Institute of Technology (KIT) was actively engaged in measurements in Arctic since the end of 2015. The research team has observed vertically extended polar stratospheric clouds, in unusually low regions of the…

The 2015 ozone hole over Antarctic larger than usual and late

The annual Antarctic ozone hole was larger than usual this year and formed later than in recent years, according to the scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). The ozone hole reached its maximum on October 2, 2015,…

A sharp decline in concentration of ozone destroying HCFC-133a gas reported

A sharp decline in concentration of ozone destroying HCFC-133a gas reported

A new study lead by Martin Vollmer of the Swiss Federal Laboratories for Materials Science and Technology has found that after a rapid increase in anthropogenic compound named HCFC-133a (CF3CH2Cl), an ozone destroying gas, the atmospheric abundance and emissions…

Study links ozone hole to climate change all the way to the equator

Study links ozone hole to climate change all the way to the equator

In a study to be published in the April 21st issue of Science magazine, researchers at Columbia University’s School of Engineering and Applied Science report their findings that the ozone hole, which is located over the South Pole, has affected the entire circulation

Impact of polar ozone depletion on subtropical precipitation

Impact of polar ozone depletion on subtropical precipitation

The ozone hole over Antarctica has been rearranging rainfall patterns throughout the Southern Hemisphere for decades, a new modeling analysis shows. The idea that losing ozone in the cold stratosphere over the South Pole could affect weather in the lower atmosphere…

Developing ozone hole approaches Scandinavia and Eastern Europe right now

Developing ozone hole approaches Scandinavia and Eastern Europe right now

An exceptionally large area of depleted ozone has formed over the North Pole, and scientists warn that it could settle over Scandinavia and Eastern Europe on 30-31 March.The fast-thinning Arctic ozone layer was first detected by an international network of over 30

Arctic May Face Record Loss of Ozone This Spring

Arctic May Face Record Loss of Ozone This Spring

Cold temperatures in the upper atmosphere and the lingering presence of ozone-destroying pollutants, called chlorofluorocarbons, have set the stage for what could be a record loss in protective ozone over the Arctic this spring.Unusually low temperatures in the
