Dispersion of a neutral tracer above a urban area in Grenoble (France) is
studied with a large eddy simulation (LES) of atmospheric flows under con-
ditions of steady wind.
The complex terrain with surrounding mountains is
taken into account with a computational domain whose extension is 23Km
x 25Km x 15Km.
The tracer is emitted from a non-buoyant point source
and transported by a quasi steady wind coming from north west direction.
The results are compared with data obtained from an experiment with a
three hours steady release of SFe on June 15th, 1995.
A good agreement is
observed for tracer dilution when comparing calculated and observed val-
ues of CTA (Atmospheric Transfer Coef...
