Greenhouse Gas and Short-Lived Pollutants Measured Via Research Aircraft over New York City during AGES+ in July 2023

Urban greenhouse gas emissions play a significant role in contributing to global climate change. Short-lived pollutants contribute to local air quality and can lead to a variety of impacts on the earth and the human condition. In July 2023, the University of Maryland/NOAA Cessna research aircraft conducted eight flights sampling urban emission of greenhouse gases (CO₂ and CH_4), and short-lived pollutants (NOx, O3, PM_2.5, BC, BrC, and CO) from the New York City metropolitan area, as part of the AGES+/AEROMMA campaign. This study focused on investigating several severe ozone exceedance events and we flew patterns conducive to flux estimates from mass balance methods with well-defined urban plumes.
