Natural ozone changes suggest good news for future
(Phys.org) —New NASA research on natural ozone cycles suggests ozone levels in the lowest part of Earth's atmosphere probably won't be affected much by projected future strengthening of the circulating ...
New sensor improves the level of efficiency in detecting ozone
Researchers from the Universitat Jaume I in Castelló, the São Paulo State University in Brasil and the Aix-Marseille University in France have developed a more effective ozone sensor than the ones used ...
Researchers find that the extremes in Antarctic ozone holes have not been matched in the Arctic
Since the discovery of the Antarctic ozone hole, scientists, policymakers, and the public have wondered whether we might someday see a similarly extreme depletion of ozone over the Arctic.
NASA simulation portrays ozone intrusions from aloft
(Phys.org) —Outdoor enthusiasts in Colorado's Front Range are occasionally rewarded with remarkable visibility brought about by dry, clear air and wind. But it's what people in the mountainous U.S. West ...
Little-studied man-made gases have big warming potential
(Phys.org) —The total warming impact of 25 major synthetic greenhouse gases has been examined by an international team, led by researchers from the University of Bristol.
Previously unknown atmospheric phenomenon discovered
Recent research results show that an atmospheric hole over the tropical West Pacific is reinforcing ozone depletion in the polar regions and could have a significant influence on the climate of the Earth.
Disinfecting honey comb with ozone
Sometimes even honey bees need help with "housekeeping," especially when it comes to cleaning their honeycombs once the honey's been removed. U.S. Department of Agriculture (USDA) research has shown that ...
How wind helps Antarctic sea ice grow, even as the Arctic melts
Strong winds linked to climate change and the hole in the ozone layer are driving a steady increase in Antarctic sea ice, even as Arctic levels continue to shrink dramatically, a new report shows.
Study reveals four new man-made gases in the atmosphere
Scientists at the University of East Anglia have identified four new man-made gases in the atmosphere – all of which are contributing to the destruction of the ozone layer.
Asian ozone pollution in Hawaii is tied to climate variability
(Phys.org) —Air pollution from Asia has been rising for several decades but Hawaii had seemed to escape the ozone pollution that drifts east with the springtime winds. Now a team of researchers has found ...
Conifer scent influences climate
(Phys.org) —Conifers emit volatile hydrocarbons, primarily terpenes, which we experience as the characteristic smell of the woods. In a complicated series of reactions involving ozone and sulfur dioxide, ...
NASA reveals new results from inside the ozone hole
NASA scientists have revealed the inner workings of the ozone hole that forms annually over Antarctica and found that declining chlorine in the stratosphere has not yet caused a recovery of the ozone hole.
Climate tracking experiment celebrates 10 years
Scientists, industry and government representatives gathered at the University of Toronto recently for the 10-year anniversary of the successful Atmospheric Chemistry Experiment known as ACE.
South Pole ozone hole slightly smaller this year (Update)
Scientists say warm upper air this September and October helped shrink the man-made ozone hole near the South Pole slightly.
