The Multi-Angle Imager for Aerosols (MAIA) was selected for launch by NASA under its Earth Venture program and is scheduled for launch in 2022. Its mission is to combine MAIA measurements with a chemical transport model and population health records to better understand the connections between aerosol pollutants and health problems such as adverse birth outcomes, cardiovascular and respiratory diseases, and premature deaths. You can learn more about MAIA at the official MAIA website hosted at JPL.
The MAIA satellite instrument is a high-resolution, multi-spectral, multi-angle, polarimetric imaging system. Multi-angle imaging is had using a two-axis gimbal, which provides along-track and cross-track pointing capabilities. The animation below (credit JPL) demonstrates MAIA’s sampling strategy over the LA Primary Target Area – one of a dozen large cities designated as Primary Target Areas.
Technology demonstration for MAIA was demonstrated as part of the Airborne Multiangle SpectroPolarimetric Imager (AirMSPI) program at JPL. Our group helped the AirMSPI team in various field campaigns, including SEAC4RS and PODEX. At times, this can be a lot of fun and scary as shown in the
with Prof. Di Girolamo in the NASA chase car. The driver of the chase car is also a pilot and is feeding the ER-2 pilot landing information, while the rest of us in the car are getting ready to jump out of the car just before the ER-2 stops so that we can run out and grab both wings so that the plane doesn’t tilt over. (no kidding).
Like MISR, Prof. Di Girolamo is a Co-I of the MAIA mission. Our group’s responsibility to the MAIA mission is to develop the MAIA cloud detection algorithm and to help ensure that the assessment of air pollutants on human health properly accounts for cloud-aerosol co-variability.
The MAIA project is supported by the Jet Propulsion Laboratory under contract with NASA. The publications below on aerosols include support from other contract under NASA or NSF and are listed int he acknowledgement section of the publication.
