environmental compartment, are not taken into account: dry and wet deposition on
the ground, washout due to precipitation, and multi-species reactions. More specif-
ically, all decay processes are neglected for which a first order description does not
suffice. For example, photochemical degradation, that is relevant in air pollution
problems, requires a more detailed approach.
The following commands deliver the result of a Gaussian plume according to
formula (

).
The command sequence is included in the accompanying software in file
'GaussianPlume.m'
.
The results of the commands, slightly modified in the MATLAB
figure editor,
are shown in Figs.
16.7
and
16.8
. The first figure depicts the concentration on the
ground. Highest concentrations on the ground can be observed approximately
300 m downstream from the stack. In analogy to the 1D situation analytical
