Atmospheric Emissions and Reactions Observed from Megacities to Marine Areas (AEROMMA) is a comprehensive study led by NOAA’s Chemical Sciences Laboratory investigating anthropogenic and marine emissions that alter tropospheric composition and impact air quality and climate.
The AEROMMA project addresses emerging research needs in urban air quality, marine chemistry influences on cloud formation, and interactions at the marine-urban interface.
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].
