Atmospheric Turbulence and Diffusion Division – Oak Ridge, Tennessee

The Atmospheric Turbulence and Diffusion Division (ATDD) conducts research and development in the fields of air quality, atmospheric dispersion, and climate science. Within each of these, emphasis is placed on the lowest part of the atmosphere closest to and most influenced by the ground — the atmospheric boundary layer.

ATDD’s air quality research focuses on developing better methods for understanding atmospheric chemistry and the exchange of air pollutants between the air and the underlying surface. The dispersion research focuses on providing critical data and insights about turbulence in the atmospheric boundary layer and transport and diffusion of harmful material. The climate research focuses on providing long-term, high quality, reference-grade measurements of critical climate parameters, such as air temperature, precipitation, winds, land surface temperature, and solar radiation.

ATDD scientists and engineers undertake short-term and long-term studies across the U.S., as well as operate two permanent, long-term research stations in Oak Ridge: a station in the Walker Branch Watershed and a station at the Chestnut Ridge Environmental Study Site. The ATDD is heavily supported by staff on assignment from the Oak Ridge Associated Universities

Directions from McGhee Tyson (Knoxville) Airport

  • From the airport, drive about 3 miles on US-129 N towards Interstate 140
  • Take the I-140 W ramp towards Oak Ridge
  • Stay on I-140 W for about 11 miles
  • After crossing over Interstate 40, I-140 W ends and becomes TN-162 N; stay on TN-162 for about 5.5 miles to Solway
  • Just before Solway follow TN-62 which forks off to the left into Solway
  • From Solway, drive approximately 5 miles on TN-62 to the ATDD facility (on the left just past Ole Ben Franklin Motors)
