DC3: Chemistry of Thunderstorms
May 9, 2012 — NASA researchers are about to fly off on a campaign that will take them into the heart of thunderstorm country. The Deep Convective Clouds and Chemistry (DC3) field campaign will use an airport in ... > full story -
Japan Shares Space Station SMILES Via Atmospheric Data Distribution
March 20, 2012 — Did you panic when you heard in recent news that two massive solar flares from the Sun were hitting Earth's atmosphere? The coronal mass ejections, or CMEs, typically produced by solar flares might ... > full story -
Sea Ice Drives Arctic Air Pollutants, NASA Finds
March 1, 2012 — Drastic reductions in Arctic sea ice in the last decade may be intensifying the chemical release of bromine into the atmosphere, resulting in ground-level ozone depletion and the deposit of toxic ... > full story -
CFC Substitutes: Good for the Ozone Layer, Bad for Climate?
February 24, 2012 — The Montreal Protocol led to a global phase-out of most substances that deplete the ozone layer, such as chlorofluorocarbons (CFCs). A happy side-effect of the gradual ban of these products is that ... > full story -

February 14, 2012 — Short-term exposure (for up to 7 days) to all major air pollutants, with the exception of ozone, is significantly associated with an increased risk of heart attack, according to a new review ... > full story -
Coastal Waters Produce Halogenated Organic Molecules That Exacerbate Stratospheric Ozone Depletion
February 1, 2012 — Coastal waters of the tropical Western Pacific produce natural halogenated organic molecules involving chlorine, bromine and iodine atoms that may damage the stratospheric ozone layer. This is the ... > full story -
New Study Sheds Light on Evolutionary Origin of Oxygen-Based Cellular Respiration
January 22, 2012 — Researchers in Japan have clarified the crystal structure of quinol dependent nitric oxide reductase (qNOR), a bacterial enzyme that offers clues on the origins of our earliest oxygen-breathing ... > full story -
Low Temperatures Enhance Ozone Degradation Above the Arctic
January 19, 2012 — Extraordinarily cold temperatures in the winter of 2010/2011 caused the most massive destruction of the ozone layer above the Arctic so far: The mechanisms leading to the first ozone hole above the ... > full story -
Historic Spanish Analysis of Atmospheric Ozone Highlights the Importance of Chlorofluorocarbon Gases
December 5, 2011 — Researchers have rebuilt the ozone column trends recorded between 1978 and 2008 that rise up over the Iberian Peninsula. The results highlight the influence that the prohibition of aerosols and ... > full story -
