Project: ASIA-AQ

The Atmospheric Science Data Center (ASDC) has released data for the Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ) campaign. ASIA-AQ was an international cooperative field study designed to address local air quality challenges. Conducted from January-March 2024, ASIA-AQ deployed multiple aircraft to collect in situ and remote sensing measurements, along with numerous ground-based observations and modeling assessments. Data collection took place across four countries including the Philippines, Taiwan, South Korea, and Thailand, with flights conducted in full partnership with local scientists and environmental agencies responsible for air quality monitoring and assessment. One of the primary goals of ASIA-AQ was to contribute to improving integration of satellite observations with existing air quality ground monitoring and modeling efforts across Asia. South Korea’s Geostationary Environment Monitoring Spectrometer (GEMS) provides hourly observations of air quality for both trace gases and aerosols and can observe all or part of twenty-two countries. Other ASIA-AQ science goals focused on satellite validation and interpretation, emissions quantification and verification, model evaluation, aerosol chemistry, and ozone chemistry. A more detailed explanation of ASIA-AQ and its datasets can be found on the ASIA-AQ landing page linked below.
