Boundary layer parametrization for atmospheric diffusion models by meteorological measurements at ground level

Summary Over recent years several theoretical and experimental works have made it possible to evaluate the basic parameters describing the atmospheric boundary layer by means of elementary meteorological measurements in proximity to the ground. This has opened up the possibility of utilizing atmospheric pollutant dispersion models able to use direct evaluations of atmospheric turbulence through friction velocity and the Monin-Obukhov length. The present paper provides an application of these new techniques in the Milan area.
