A team of scientists has successfully flown from the Arctic to the Antarctic this month, the first step in a three-year project to make the most extensive airborne measurements of carbon dioxide and other greenhouse gases to date.

NCAR postdoctoral researcher Yongku Kim is using epidemiologic data to study the effects of ozone regulation on human health. He’s leading an assessment of how various regulatory standards for ozone may affect non-accidental mortality, including respiratory-related deaths during ozone season.

Wildfires can boost ozone pollution to levels that violate U.S. health standards, a new study concludes.

Research from MIRAGE (Megacities Impacts on Regional and Global Environments), a field campaign held in Mexico City in 2006, is coming to fruition as scientists begin to publish their findings. A new paper details the ozone “weekend effect” in Mexico City and its implications for local air pollution.

Mountain pine beetles appear to be doing more than killing large swaths of forests in the Rocky Mountains. Scientists suspect they are also altering local weather patterns and air quality.
