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.
The NOAA/OAR Climate Program Office’s AC4, ERB and CVP Programs will host an info session on Wednesday, July 26th from 1:00 to 2:00 p.m. ET on our programs and new funding opportunities.

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.
New research illustrates a reduction in greenhouse gas emissions from six North American cities because of a reduction in traffic and economic activities during COVID-19 lockdown.
