The NASA DC-8, the world's largest flying chemistry laboratory, is the flagship of AEROMMA. The research aircraft will base out of Palmdale, CA to access the urban areas of Los Angeles together with regions where DMS chemistry is known to be active off the coast of Los Angeles and the Salton Sea. The second half of the mission will be based in the Eastern U.S. to survey major urban areas such as New York, Chicago, and Atlanta, together with agricultural regions in Wisconsin, Iowa and Illinois.
The NOAA Twin Otter will coordinate closely with the NASA DC-8 for the Coastal Urban Plume Dynamics Study (CUPiDS). The aircraft will carry atmospheric remote sensing instrumentation to make observations from the New York City region to study diurnal forcing of atmospheric dynamics on urban plume transport and mixing in coastal regions.
The NOAA Ship Ronald H. Brown is proposed for mobile ground-based observations off the U.S. southwest Pacific coast for AEROMMA. The research vessel would be positioned along the coast in regions of high DMS emissions and onshore flow for marine studies, and positioned downwind of urban sources (e.g., Los Angeles, Long Beach) for urban studies during AEROMMA.
The NASA / SAO (Smithsonian Astrophysical Observatory) TEMPO (Tropospheric Emissions: Monitoring Pollution) instrument is a UV-visible spectrometer, and will be the first ever space-based instrument to monitor air pollutants hourly across the North American continent during daytime. It will collect high-resolution measurements of ozone, nitrogen dioxide and other pollutants, data which will revolutionize air quality forecasts. TEMPO observations are from the geostationary vantage point, flying on a telecommunications host spacecraft with a scheduled launch in January of 2023.
