Multi-Angle Imager for Aerosols (EVI-3) (MAIA)
Status:
Future, Implementation
Mission Category:
Earth System Science Pathfinder Program, Earth Venture Class, Earth Venture-Instrument
Launch Date: November 2025
The Multi-Angle Imager for Aerosols (MAIA) uses a twin-camera instrument that will make radiometric and polarimetric measurements needed to characterize the sizes, compositions and quantities of particulate matter in air pollution. As part of the MAIA investigation, researchers will combine MAIA measurements with 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.
The MAIA instrument measures the radiance and polarization of sunlight scattered by atmospheric aerosols, from which the abundance and characteristics of ground-level particulate matter (PM) are derived. The instrument contains two pushbroom spectropolarimetric cameras on a two-axis gimbal for multiangle viewing, frequent target revisits, and inflight calibration.
