The Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ) was an international cooperative investigation to study the factors contributing to local air quality across Asia. Measurements from ASIA-AQ were collected to validate aerosol satellite observations from South Korea’s Geostationary Environment Monitoring Spectrometer (GEMS), the upcoming Multi-Angle Imager for Aerosols (MAIA) mission, and other low-orbiting satellites. ASIA-AQ had one deployment from January to April 2024 across eastern Asia mainly targeting South Korea, Philippines, and Thailand.
