Giles County, TN Wind Profiler Data contains vertical wind profiles collected during the 1995 Southern Oxidants Study (SOS) field campaign. The Tennessee Valley Authority coordinated the study, which ran from June 21 to July 21, 1995. Data was gathered using a 915 MHz Doppler radar to investigate processes controlling tropospheric ozone production.
Use Cases
- Analyze vertical wind shear and its influence on local ozone distribution using 60 incremental altitude levels.
- Model pollutant transport dynamics by correlating consensus wind values with concurrent ozone measurements from the SOS study.
- Validate or train atmospheric dispersion models with wind profile data spanning from 112 m to approximately 3 km above ground level.
- Study diurnal or event-driven changes in boundary layer winds using time-series data collected over the month-long campaign.
Strengths
- Data covers a focused, intensive field campaign period of one month (June 21 to July 21, 1995).
- Vertical profiles provide high-resolution wind data at 60 altitude increments in 56-meter steps.
- Wind values are derived from a consensus algorithm applied to 30 consecutive radar pulse sets per measurement.
Limitations
- Temporal coverage is limited to a single month in 1995, restricting analysis of long-term trends.
- Geographic scope is confined to a single profiler site in Giles County, Tennessee.
- Data freshness is low, with the last update recorded in July 1995.
