LISTOS Outer Island Ground Site Data contains atmospheric measurements from the Long Island Sound Tropospheric Ozone Study field campaign. The dataset was produced by a multi-agency collaboration including NASA, NOAA, EPA NESCAUM, and state environmental departments. Primary observations were collected between June and September 2018.
Use Cases
- Analyze temporal trends in ground-level ozone concentration from Outer Island measurements.
- Study the correlation between sea breeze events and transported NO2 or HCHO pollution levels.
- Validate satellite-based Tropospheric Monitoring Instrument (TROPOMI) science products using ground-based ozone and NO2 data.
- Investigate pollution transport from the New York City metropolitan area over Long Island Sound using ground site observations.
Strengths
- Data collection involved a coordinated multi-agency effort including NASA, NOAA, and multiple state environmental departments.
- Measurements are focused on a specific, chronic air quality problem in a densely populated region of over 20 million people.
- Campaign integrated data from aircraft, ground sites, mobile vehicles, and boats for a multi-platform perspective.
Limitations
- Dataset is limited to a single ground site location (Outer Island).
- Temporal coverage is confined to a 4-month campaign period in 2018.
- Specific row count, column details, and measurement frequency are not provided.
