LISTOS: Aircraft In-Situ Air Quality Measurements Over Long Island Sound

LISTOS_AircraftInSitu_UMDAircraft_Data is in-situ data collected onboard a University of Maryland Cessna aircraft during the Long Island Sound Tropospheric Ozone Study. The multi-agency campaign, led by NASA, NOAA, EPA, and state environmental departments, took place between June and September 2018 to investigate ozone formation and transport. Data collection is complete and was used to validate satellite instruments like TEMPO and TROPOMI.

Use Cases

• Model ozone formation and transport based on in-situ aircraft measurements over Long Island Sound.
• Validate satellite-derived air quality products like TROPOMI NO2 and HCHO using airborne observations.
• Study the impact of sea breeze circulation on pollutant confinement and inland transport.
• Analyze the chronic ozone problem in the New York City metropolitan area and downwind states.
• Test airborne simulator instruments like GCAS and GeoTASO for future geostationary satellite missions.

Strengths

• Data collection is complete for the primary measurement period between June-September 2018.
• Result of a joint effort across multiple agencies including NASA, NOAA, EPA, and several state environmental departments.
• Includes measurements from a network of ground sites, mobile vehicles, boats, and ozonesondes alongside aircraft data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• File formats include BIN, PDF, ISO, HTML; data accessibility may require specialized tools.
