Atlanta is a hot-spot of both ozone and SOA, and much of the summer is typically classified as "moderate" according to the air quality index. The city is subject to high anthropogenic and biogenic emissions along with increasingly severe heat waves. Atlanta has been the location of several previous studies investigating biogenic/anthropogenic interactions, including flights during Southeast Nexus (SENEX) 2013 and Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS). AEROMMA allows us to build on and update previous work with new chemical detail. Ground-based observations will overlap the AEROMMA flights.
Using these observations in conjunction with observations from overhead flights, the project will address the central questions to AEROMMA with a focus on the biosphere/urban interface.
