June 19 to July 28, 1995, this dataset contains continuous 5-minute measurements of ozone, nitrogen oxides, carbon monoxide, and sulfur dioxide from seven monitoring stations in the Nashville/Middle Tennessee region. The Tennessee Valley Authority coordinated the Southern Oxidants Study field campaign to improve understanding of tropospheric ozone production. Midday canister samples for volatile organic compounds were also collected and analyzed by the University of Miami.
Use Cases
- Analyze diurnal patterns of ozone (O3) concentrations in relation to 5-minute meteorological data like wind speed and solar radiation.
- Investigate correlations between nitrogen oxide species (NO/NOy/NO2) and volatile organic compound (VOC) samples to study ozone precursor relationships.
- Model the spatial distribution of pollutants like sulfur dioxide (SO2) and carbon monoxide (CO) across the seven monitoring station locations.
- Validate chemical transport models using concurrent, speciated measurements of multiple air pollutants from a coordinated field campaign.
Strengths
- High-temporal-resolution 5-minute measurements for core pollutants.
- Multi-pollutant coverage including O3, NOx, CO, SO2, and VOC samples.
- Data collected from seven distinct monitoring sites across Tennessee and Kentucky.
Limitations
- Data is limited to a specific six-week period in summer 1995.
- The exact row count and data completeness for each station are unknown.
- Geographic coverage is focused on one region, limiting broader applicability.
