“…8 and 11 quite well by adjusting the constants A and B, consistent with results given by, for instance, Mole and Clarke (1995) and Schopflocher and Sullivan (2005). In our case the fit is performed for several datasets as outlined in Sect.…”

“…8 and 11. This result is consistent with other results (Mole and Clarke 1995;Schopflocher and Sullivan 2005), but they are here found for Lidar-averaged data with two types of analysis, the fixed and centre-of-mass systems, as defined here. We find it interesting that also an empirical relation between σ 2 /C 2 and S can be found (see Figs.…”

“…When λ j = 1 for all j, the expressions (3)-(5) contain the exact results for the model with the initial concentration being either C m or zero (Csanady 1967;Mole and Clarke 1995;Yee and Chan 1997), where the probability for a vanishing concentration is P(c = 0) = 1 − α(y, t), while the probability for detecting a concentration C m is P(c = C m ) = α(y, t), giving…”

Near-ground artificial cloud releases in the turbulent atmospheric boundary layer were investigated experimentally by Lidar measurement techniques. Simple scaling relations between the average concentration and the lowest order moments are suggested by simple analytical models, and the experimental results are tested against these hypotheses. We find strong evidence for a simple scaling of the standard deviation, skewness and kurtosis with the average concentrations at the downwind distances observed in our experiments. Near-ground concentration fluctuations in fixed as well as moving frames of references are investigated. The scaling is supported by data from several experimental sites and different atmospheric stability conditions. One conclusion of the study is that relatively accurate estimates for the standard deviation, skewness and kurtosis can be obtained for the concentration fluctuations, given a reliable estimate of the space-time varying average concentration field.
