AMS honors Huang presentation

Guanyu Huang, a doctoral candidate in atmospheric science at UAH, has been honored by the American Meteorological Society for a scientific talk he presented in Atlanta at the recent AMS annual meeting.

His talk, “A sensitivity study of ozone entrainment flux on boundary layer micrometeorology fields” to the AMS’ 18th Joint Conference on the Applications of Air Pollution Meteorology was selected as the presentation with the best technical content.

Working with Dr. Mike Newchurch, Huang is studying how turbulence between the atmosphere’s cool boundary layer, which forms at night near the surface, and the troposphere above it contributes to trapping and transporting ozone close to the ground.

“It could be a large contributor to air pollution problems,” he said. “Some research says the ozone trapped as the boundary layer forms could be responsible for 70 to 80 percent of ozone pollution near the surface the following day.”

Huang and Newchurch use turbulence models and a pair of lidars — one that measures ozone and another that tracks air movement — to study ozone movement along the top edge of the boundary layer.
