LISTOS Westport Ground Site Data contains atmospheric measurements from the Long Island Sound Tropospheric Ozone Study field campaign. The multi-agency effort involved NASA, NOAA, EPA NESCAUM, and state environmental departments, with primary data collection occurring between June and September 2018. It focuses on ozone formation and transport in the New York City metropolitan area and downwind regions.
Use Cases
- Analyze temporal trends in ground-level ozone concentrations from the Westport site to study daily and seasonal pollution patterns.
- Correlate ozone measurements with meteorological data like sea breeze events to model pollution transport over Long Island Sound.
- Validate satellite-derived NO2 and HCHO science products from TROPOMI using coordinated ground-based measurements.
- Investigate the relationship between ozone levels and precursor pollutants measured at the ground site to improve chemical transport models.
- Assess air quality impacts on coastal Connecticut by studying ozone data linked to pollution confined in the marine boundary layer.
Strengths
- Data collection involved a coordinated multi-agency campaign including NASA, NOAA, and multiple state environmental departments.
- Campaign integrated measurements from ground sites, aircraft, mobile vehicles, and boats for a multi-platform perspective.
- Focused temporal coverage during peak ozone season from June to September 2018.
Limitations
- Specific row count, column details, and measurement frequency for the Westport site are not provided.
- Geographic scope is limited to a specific ground site in Westport within the broader Long Island Sound region.
- Data is from a single field campaign in 2018, limiting analysis of long-term trends or interannual variability.
