Turbulent transport in the atmospheric surface layer

Figure 1. The estimated deposition velocity versus the stability parameter for the unstable stratified flows. The experimental data for the sulfur aerosols by Labatut et al are shown by the square symbols. The ozone deposition data are shown in the right bottom part.
