The Southern Oxidants Study (SOS) Nashville/Middle Tennessee Ozone Study Data Base contains measurements of biogenic volatile organic compounds and related atmospheric variables. Data was collected from July 13 to July 21, 1995, at a predominantly oak forest site by Oak Ridge National Laboratory as part of a Tennessee Valley Authority-coordinated field campaign. Measurements span leaf-level, canopy-level, and landscape-level scales.
Use Cases
- Modeling isoprene emission rates using concurrent measurements of temperature, photosynthetically active radiation (PAR), and vegetation species data.
- Analyzing relationships between ozone concentration and flux and precursor compounds like methyl vinyl ketone and methacrolein.
- Investigating forest canopy exchange processes by correlating CO2 and water vapor flux data with wind speed/direction, humidity, and net radiation.
- Studying the impact of UV-b radiation on the production of inorganic and organic peroxide concentrations.
- Characterizing non-methane hydrocarbon (NMHC) profiles from a specific oak forest environment using the collected survey data.
Strengths
- Multi-scale measurements covering leaf-level, canopy-level, and landscape-level processes.
- Comprehensive suite of over 15 measured variables including VOCs, meteorological data, radiation, and flux measurements.
Limitations
- Very short temporal coverage limited to a 9-day period in July 1995.
- Geographic scope is restricted to a single forest site in Middle Tennessee, limiting generalizability.
- Sample size and data volume are unknown, potentially limiting statistical power for some analyses.
