NASA has selected two Earth Venture Instrument projects for launch in the 2022 timeframe which will provide data of interest to the health and air quality communities. The NASA Multi-angle Imager for Aerosols (MAIA) instrument is currently in development at the Jet Propulsion Laboratory, and will be launched into low-Earth polar orbit. MAIA will provide high spatial resolution speciated PM products over a set of globally distributed target areas. The Tropospheric Emissions: Monitoring Pollution (TEMPO) project will provide high temporal resolution measurements of ozone, nitrogen dioxide, formaldehyde, and other key species critical to air pollution over North America from geostationary orbit. This town hall will provide an opportunity for epidemiologists, environmental health researchers, air quality managers, and other interested people to hear from members of the MAIA and TEMPO teams and the NASA Applied Science Program about the investigations and opportunities to get involved as an Early Adopter.
