June-September 2018 data from the Long Island Sound Tropospheric Ozone Study (LISTOS) field campaign. It contains ground-based measurements of pollutants like ozone, NO2, and HCHO collected at miscellaneous sites around Long Island Sound. The dataset is a multi-agency product from NASA, NOAA, EPA NESCAUM, and several state environmental departments and university research groups.
Use Cases
- Analyze temporal trends in ground-level ozone concentrations from the 2018 summer period.
- Validate satellite-based air quality products from TEMPO or TROPOMI using ground-based NO2 and HCHO measurements.
- Study the impact of sea breeze circulation on pollutant transport by correlating ozone readings with coastal and inland site data.
- Investigate regional ozone chemistry by examining co-located measurements of ozone, NO2, and HCHO from the ground site network.
Strengths
- Data collection involved a coordinated multi-agency effort including NASA, NOAA, and multiple state environmental agencies.
- Measurements are focused on a specific, high-impact 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
- Temporal coverage is limited to a single summer season (June-September 2018).
- Specific row count, column details, and data completeness for ground sites are unknown.
- Geographic scope is focused on the Long Island Sound region, limiting broader applicability.
