LISTOS Hammonasset Ground Site: Air Quality Measurements from 2018 Field Campaign

The New York City metropolitan area and downwind states face persistent challenges meeting federal ozone standards. LISTOS_Ground_Hammonasset_Data contains ground site measurements collected at Hammonasset during the Long Island Sound Tropospheric Ozone Study (LISTOS) field campaign from June to September 2018. The data is a result of a multi-agency collaboration involving NASA, NOAA, EPA NESCAUM, and several state environmental departments and university research groups.

Use Cases

• Analyze ozone transport patterns based on the described sea breeze circulation over Long Island Sound.
• Validate satellite-based air quality retrievals (e.g., TEMPO, TROPOMI) using the ground-based measurements of ozone, NO2, and HCHO.
• Study the impact of pollution confinement in the shallow marine boundary layer on local ozone concentrations.
• Investigate the evolving nature of ozone formation in the NYC region based on the multi-instrument campaign observations.

Strengths

• Data collection is complete for the primary measurement period between June-September 2018.
• Result of a joint effort across multiple authoritative agencies including NASA, NOAA, EPA, and state environmental departments.
• Integrated with a broader campaign network including aircraft, mobile vehicles, boats, and ozonesondes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Available file formats (BIN, PDF, ISO, HTML) suggest raw or packaged data requiring specialized tools for access.
