The data report presents results from two diffusion experiments conducted at the Boulder Atmospheric Observatory (BAO) in 1982 and 1983. The objective was to compare diffusion in the atmospheric convective boundary layer with that observed in laboratory tank experiments and numerical computer models. In both experiments at the BAO, two different tracers, oil fog and aluminized chaff, were released simultaneously and tracked by lidar and radar, respectively, for periods up to two hours. In 1982, both tracers were released from the same surface or elevated point; in 1983, the two were also released from separate levels, the oil fog from near the surface, the chaff from an elevated point on the tower. The 1983 experiment included tracer gas releases with in situ samplers measuring surface concentrations downwind of the tower. The BAO tower provided data on the mean and turbulent state of the atmosphere, while mixing depths were monitored by balloon soundings, sodar, lidar and radar. A detailed description of the experiment and the measurements obtained from the different sensors is provided. The strengths and limitations of the experiment are discussed in the context of case studies.
