June 27 to July 20, 1995 data from airborne experiments conducted by the DOE's Pacific Northwest and Brookhaven National Laboratories using a Grumman G-1 aircraft. The dataset documents urban plume chemistry, power plant plume encounters, and regional background measurements during the Southern Oxidants Study in Nashville/Middle Tennessee. The goal was to improve scientific understanding of tropospheric ozone production and distribution processes.
Use Cases
- Model ozone production rates using time-series measurements of precursor concentrations from urban plume flights.
- Analyze chemical transformation within power plant plumes by tracking species ratios across flight paths.
- Characterize regional background air composition using data from vertical spiral profiles over ground sites.
- Study diurnal variations in tropospheric chemistry by correlating flight timing with measured pollutant levels.
Strengths
- Data collected during a focused, 24-day major field campaign in summer 1995.
- Measurements target specific phenomena: urban plumes, power plant plumes, and regional background.
Limitations
- Dataset is over 25 years old, limiting relevance for contemporary pollution studies without complementary modern data.
- Specific sample size, measured variables, and data resolution are unknown from the description.
