A new AC4-funded study on atmospheric ozone production uses field observations to investigate changes in ozone production on high ozone concentration days during the summer of 2018.

AC4 funded research uses unprecedented field measurements to gather data on real-world vehicular and non-vehicular volatile organic compound (VOC) emissions to characterize emission rates and oxidative aging of various types of organic pollutants and greenhouse gases in the Greater New York City Metropolitan Area.

Drought conditions lead to an increase in summertime ozone in the U.S. Southeast but not the West, highlighting the long-term impact of droughts on atmospheric composition.

Stratospheric ozone information is consistently measured to a high degree of accuracy and can now be used for seasonal forecasting in North America which has major applications such as informing public health and agricultural decisions.
