Researchers supported by AC4 conduct observations over 9 months to examine pollution sources that lead to secondary organic aerosol production in Atlanta.
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.
Approximately $11.1 million will be available in FY23 to start new awards in about six different topic areas, pending budget appropriations.
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.
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.
