Nashville/Davidson County soil nitrogen oxide (NOx) emission measurements were collected at 13 locations in August 1995. The Tennessee Valley Authority coordinated this survey as part of the Southern Oxidants Study to assess biogenic contributions to ozone formation. Data indicates urban soil contributed a minimal fraction of total county NOx emissions.
Use Cases
- Estimate county-wide biogenic NOx contributions by extrapolating emission rates from 13 sample locations.
- Compare soil NOx emission rates across managed urban land use types like lawns, gardens, parks, and golf courses.
- Model the relative impact of soil emissions versus other sources using the provided percentage contributions for Davidson and surrounding counties.
Strengths
- Data collection targeted 13 specific locations, providing a structured survey of urban land use types.
- Study provides concrete quantitative findings, such as urban soil contributing only 0.003% of total county NOx emissions.
Limitations
- The dataset is small, with measurements from only 13 locations, limiting statistical power.
- Data is temporally limited to a single month (August 1995) and may not represent seasonal or annual trends.
- Geographic scope is focused on one county, potentially limiting generalizability to other urban areas.
