Utilize a wind tunnel to conduct a series of wind flow simulations over model scale terrain and structures to determine the wind flow patterns over complex agricultural sites that include buildings. Conduct lidar measurements of particulates and water vapor coupled with turbulence measurements obtained from sonic anemometers to characterize the turbulence regime in limited fetch environments. Evaluate the potential of using open path FTIR measurements to compliment the lidar measurements in the development of improved emission and dispersion models. Conduct studies on ammonia and nitrous oxide emission from controlled laboratory studies using soil columns and various manure application practices coupled with field studies to ascertain the impact of different soil and cropping management practices on these emissions. Collect particulate samples using samplers located at various positions from different livestock production facilities to determine the variation of particulate concentration and the VOC compounds attached to the particulates.
