LISTOS Westport Ground Site: Tropospheric Ozone Measurements for Long Island Sound

LISTOS Westport Ground Site Data is part of the Long Island Sound Tropospheric Ozone Study, a multi-agency effort involving NASA, NOAA, EPA, and state environmental departments. Primary measurements were collected between June and September 2018 using a network of ground sites, aircraft, mobile vehicles, boats, and ozonesondes. The study aimed to improve understanding of ozone chemistry and pollution transport over Long Island Sound and its coastlines.

Use Cases

• Analyze ozone formation and transport patterns based on ground-level ozone measurements mentioned in the description
• Validate satellite-based air quality retrievals (e.g., TEMPO, TROPOMI) based on the use of airborne- and ground-based measurements of ozone, NO2, and HCHO
• Study the impact of sea breeze circulation on pollution inland based on the description of pollutants confined in a marine boundary layer
• Investigate chronic ozone problems in the NYC metropolitan area based on the description of persistent challenges meeting air quality standards

Strengths

• Data collection involved a multi-agency collaboration including NASA, NOAA, EPA, and multiple state environmental departments
• Primary measurement observations took place during a focused campaign between June-September 2018
• Integrated data from multiple platforms: three aircraft, a network of ground sites, mobile vehicles, boat measurements, and ozonesondes

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, which may require specialized tools for processing
