This new AC4-supported study produces a detailed comparative analysis of oxidation reactions that break down certain molecules into secondary organic aerosols, which impact air quality, climate, and human health.
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.
In winter 2022, about fifty scientists from the United States and Europe completed a seven-week atmospheric chemistry study of Fairbanks, Alaska–the state’s second-largest city.
The study, called the Alaskan Layered Pollution and Chemical Analysis (ALPACA) project, investigated the chemistry of Fairbanks’s air pollution–especially how the pollution behaves in the cold and dark.
Methane emissions trends for North America may be higher than reported by national inventories, primarily due to underestimation in emissions from the oil sector.
New results from the FIREX-AQ field campaign provide detailed insight to ozone formation in western US wildfires.
Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather.
