LISTOS Aircraft In-Situ Measurements for Ozone Transport Study

In-situ atmospheric data was collected onboard a University of Maryland Cessna aircraft during the Long Island Sound Tropospheric Ozone Study (LISTOS) field campaign. The multi-agency effort involved NASA, NOAA, EPA NESCAUM, and several state environmental departments and universities. Primary measurement observations took place between June and September 2018.

Use Cases

• Analyze vertical profiles of ozone, NO2, and HCHO concentrations from aircraft in-situ measurements to study ozone chemistry.
• Map pollution transport patterns over Long Island Sound using geospatial and time-series data to understand sea breeze effects.
• Validate Tropospheric Emissions: Monitoring of Pollution (TEMPO) satellite retrievals with coincident airborne in-situ observations.
• Investigate the correlation between marine boundary layer stability and high ozone concentrations in downwind coastal areas like Connecticut.

Strengths

• Data collection involved a coordinated multi-agency effort including NASA, NOAA, and multiple state environmental agencies.
• Campaign utilized integrated in-situ and remote sensing instrumentation aboard three aircraft alongside ground sites and mobile platforms.
• Focused temporal coverage during peak ozone season from June to September 2018.

Limitations

• Specific data volume, row count, and column details are unknown, limiting initial assessment of scope.
• Geographic coverage is restricted to the Northeast US, specifically the Long Island Sound region, limiting broader applicability.
• Data is from a single field campaign in 2018 and may not represent current or interannual atmospheric conditions.
