ASIA-AQ: In-Situ Cloud Data from DC-8 Aircraft Campaign

In-situ cloud data was collected onboard a DC-8 aircraft during the Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ) campaign. The dataset features measurements from instruments including a Condensation Nuclei Counter, Cloud Droplet Probe, and Cloud Particle Spectrometer. Data collection is complete and was conducted from January to March 2024 over the Philippines, Taiwan, South Korea, and Thailand by the National Aeronautics and Space Administration.

Use Cases

• Validate satellite air quality observations based on in-situ airborne measurements mentioned in the description
• Study cloud microphysics and aerosol interactions based on data from the Cloud Droplet Probe and Condensation Nuclei Counter
• Quantify and verify emissions for model evaluation based on the campaign's stated science goals
• Analyze regional air quality chemistry over Asia based on data collected across four countries

Strengths

• Data collection is explicitly stated as complete
• Campaign involved international partnership with local scientists and agencies across four countries
• Measurements were taken with specialized instruments including a Cloud Particle Spectrometer with Polarized Detection

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count and data volume are unknown, which may limit suitability assessment
• File formats include JPEG, BIN, ISO, PDF, and ZIP, suggesting heterogeneous data types requiring specific tools
