Aircraft-collected in-situ data from the 2017 Lake Michigan Ozone Study field campaign investigates elevated ozone levels along the lake's coast. The dataset resulted from a multi-agency collaboration including NASA, NOAA, and the EPA. Data collection was completed during the intensive observation period from May through June 2017.
Use Cases
- Analyze ozone concentration gradients between lake and shore using in-situ ozone measurements.
- Model the influence of lake breeze airflow on pollutant transport using concurrent meteorological data.
- Validate chemical transport model forecasts for the Lake Michigan region with airborne observational data.
- Investigate relationships between precursor emissions and ozone formation using chemical species measurements from the aircraft.
Strengths
- Data originates from a coordinated, multi-agency field campaign involving NASA, NOAA, EPA, and university groups.
- Provides direct airborne in-situ observations across the Lake Michigan region during peak ozone season.
Limitations
- Temporal coverage is limited to a two-month field campaign in spring/summer 2017.
- Spatial coverage is restricted to flight paths over and around Lake Michigan, not a continuous grid.
- Specific data volume, parameters, and resolution are not detailed in the provided description.
