Researchers at NCAR and partner organizations this summer are using aircraft, ground-based sensors, computer models, and other tools to track the origins of summertime ozone, a significant health threat.

California will likely experience more large fires in forested areas this century because of rising temperatures and changes in precipitation along with development patterns, new research finds. The blazes could increase some types of fire-generated air pollution by more than half.

A new grant will help researchers measure pollution from open-fire cooking and better understand a problem that kills millions of women and children in developing countries.

Geophysical Research Letters, a leading journal in Earth science, is toasting its 40th anniversary this month with an editor-picked retrospective collection of 40 papers, including several with authors from NCAR.

Americans face the risk of a 70 percent increase in unhealthy summertime ozone events by 2050 because of factors related to climate change.
