Description

ASIA-AQ_TraceGas_AircraftInSitu_DC8_Data is the in-situ trace gas data collected onboard the DC-8 aircraft during the Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ) campaign. Data from the Trace Organic Gas Analyzer (TOGA), Whole Air Sampler (WAS), Quantum Cascade Tunable Infrared Differential Absorption Spectrometer (QC-TILDAS), Chemical Ionization Time-of-Flight Mass Spectrometer (CIT-ToF-CIMS), Differential Absorption CO, CH4, N2O Measurements (DACOM), LI-7000 Closed Path CO2/H2O Gas Analyzer (LI-7000), Los Gatos Research CO/CO2/H2O Analyzer (LGR), Airborne Cavity Enhanced Spectrometer (ACES), MIRO Multi-compound Gas Analyzer (MIRO MGA), Compact Airborne Nitrogen diOxide Experiment (CANOE), Rapid Ozone Experiment (ROZE), Proton Transfer Mass Spectrometer (PTR-MS), In Situ Airborne Formaldehyde (ISAF), and Open-Path Ammonia Laser Spectrometer (OPALS) are featured in this collection. Data collection for this product is complete.

The ASIA-AQ campaign 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 was collected over four countries including, the Philippines, Taiwan, South Korea and Thailand and flights were 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 improving integration of satellite observations with existing air quality ground monitoring and modeling efforts across Asia. Air quality observations from satellites are evolving with new capabilities from South Korea’s Geostationary Environment Monitoring Spectrometer (GEMS), which conducts hourly measurements to provide a new view of air quality conditions from space that complements and depends upon ground-based monitoring efforts of countries in its field of view. ASIA-AQ science goals focused on satellite validation and interpretation, emissions quantification and verification, model evaluation, aerosol chemistry, and ozone chemistry.
