Atmospheric Emissions and Reactions Observed from Megacities to Marine Areas (AEROMMA) is a comprehensive study led by NOAA’s Chemical Sciences Laboratory to address emerging research needs in urban air quality, marine emissions, climate feedbacks, and atmospheric interactions at the marine-urban interface and future satellite capabilities of monitoring atmospheric composition over North America.
More than 100 million Americans live in non-attainment areas for ground-level ozone.
Tropospheric ozone is a toxic air pollutant formed through reactions involving VOCs and NOx.
Volatile chemical products (VCPs) are emerging as a major urban source of petrochemical organics [McDonald et al., Science, 2018].
Oxidation of ocean-emitted dimethyl sulfide (DMS) produces sulfate aerosol, which in turn impacts albedo, cloud formation, and climate.
CSL's discovery of an additional DMS oxidation product (HPMTF) shows that the marine sulfur cycle in current models is incomplete [Veres et al., PNAS, 2020].
