Pollution flux measurements were collected during the 1995 Southern Oxidants Study field campaign in Nashville and Middle Tennessee. The dataset contains continuous 30-minute average eddy correlation flux measurements for ozone, sulfur dioxide, and carbon dioxide, along with supporting meteorological and vegetation data. The study was conducted by the NOAA Atmospheric Sciences Modeling Division and the Tennessee Valley Authority from June 22 to August 10, 1995.
Use Cases
- Model ozone flux based on concurrent measurements of wind speed, solar radiation, and temperature gradient.
- Analyze correlations between sulfur dioxide flux and supporting variables like relative humidity and surface wetness.
- Train models to infer nitric acid fluxes from measured concentration gradients between 1 and 8.5 meters.
- Characterize the surface energy budget by relating heat flux, water flux, soil flux, and net radiation measurements.
- Evaluate dry deposition models using the concurrent ozone concentration, wind direction, and precipitation data.
Strengths
- Continuous 30-minute average measurements over a 50-day period from June 22 to August 10, 1995.
- Multivariate dataset includes fluxes for three key pollutants (ozone, SO2, CO2) plus supporting meteorological and energy budget data.
- Measurements were made primarily above a uniform land cover (soybeans), reducing surface variability.
Limitations
- Temporal coverage is limited to a single summer season (1995), preventing analysis of long-term trends or seasonal cycles.
- Geographic scope is focused on one site in south central Kentucky (36.83 N, 87.03 W), limiting spatial generalizability.
- Specific sample size (row count) and data completeness for all measured variables are unknown from the description.
