Level II Enhanced Surface Chemistry Network Data from the 1995 Southern Oxidants Study (SOS) Nashville/Middle Tennessee Ozone Study Data Base

The goal of this study was to improve scientific understanding of the processes that control the production and distribution of ozone in the troposphere. During the six-week 1995 Southern Oxidants Study (SOS) Nashville/Middle Tennessee Ozone Study the Level II enhanced surface chemistry network provided real-time measurements of continuous (5-minute) high-sensitivity ozone (O3), speciated nitrogen oxides (NO/NOy/NO2), carbon monoxide (CO), and sulfur dioxide (SO2) at seven monitoring stations across middle Tennessee.

Midday pressurized canister samples for volatile organic compounds (VOC) were also collected at each Level II station and analyzed by the University of Miami (Rod Zika). Standard meteorological packages were also employed at each site recording 5-minute wind sped, wind direction, temperature, relative humidity, and solar radiation to aid in data interpretation. The monitoring sites were located at: Cove Mountain, TN Dickson, TN Nashville, TN Giles County, TN Land Between the Lakes, KY Mammoth Cave, KY Youth, Incorporated (Smyrna), TN The study was conducted from June 19, 1995 through July 28, 1995.
