Experimental Evaluation of Diffusion Parameters on a Local Scale by Means of No-Lift Balloons

Validation and physical parametrization of a Gaussian climatological model applied to a complex site

“…Balloon trajectories were tracked for each of the six Pasquill stability conditions. The trajectories (Santomauro et al, 1978) were then used to estimate the vertical and horizontal standard deviations of the diffusing pollutants. These dispersion parameters were used in the model for the elevated chimneys.…”

“…In order to improve the understanding of some of the meteorological factors relevant to air pollution and to evaluate the dispersion parameters to be used in the area for releases from elevated chimneys, six field experiments, each lasting 15 days, were carried out from 1974 to 1978. The findings from these field experiments have been described elsewhere (Anfossi et al, 1976;Anfossi et al, 1979;Santomauro et al, 1978;Bonino et al, 1980). However, a short summary of the physical conditions relevant to the model is given below.…”
