Foreground: OPAL lidar trailer and Background: mini-MOPA lidar trailer

The SOS'99 Nashville study continues the research of the Southern Oxidant Study (SOS) to provide a sound scientific foundation for pollution regulation and mitigation in the Southeastern United States. This campaign is intended to provide a better understanding of the basic chemical meteorological and transport processes that determine ozone and fine particle distributions and assist policymakers in devising optimal management strategies.

ETL contributes to this study by

• Using windprofilers to study the meteorological conditions responsible for the regional transport of pollutants.

• Operating ground-based and airborne lidars which characterize the spatial distribution, time evolution and transport of ozone and aerosols.
