In this paper, direction-dependent separation distances to protect
the neighbourhood from odour nuisance have been calculated
with two models, the Gaussian Austrian Odour Dispersion Model
AODMand the Lagrange particle diffusion model LASAT. Short-term
peak odour concentrations have been calculated either with the
stability-dependent peak-to-mean algorithm developed with
AODM (Piringer et al., 2014) or with the factor 4 e approach used
with LASAT in Germany (TA-Luft, 2002). The same emission
(Table 4) and meteorological data have been used, but atmospheric
stability is determined differently from these data (Section 2.2).
Differences in the resulting separation distances are then both due
to the different peak-to-mean concepts and to the different atmospheric
stability schemes used with the models. The results are
demonstrated for Kittsee, a rural site in the Eastern flatlands of
Austria near Bratislava. On-site meteorological conditions are presented
in Figs. 1 and 2.
