Abstract

The evaluation of the pollutant mass transport from remote sensing data in an orographically complex area requires a very detailed meteorological information. This is the case of the Fos-Berre (France) Campaign organized by the CEE on June 1983: the breeze wind circulation over this coastal area is strongly modified by the presence of sea and land surfaces, a large pond, hills and mountains so that the wind direction and speed are a function of site, elevation and time of the day. The knowledge of the three-dimensional wind field, required for a correct data processing has been restricted to the sounding stations put into operation during the Campaign. For the extension of the available data to the entire field and time of survey, we have used a suitable breeze model, based on the numerical integration of the fluidodynamic equation in an hydrostatic approximation of the planetary boundary layer. This equation takes into account effects due to (1) flow lifting and diversion over hills, (2) thermal friction, (3) tunnelling in valleys and (4) heat islands. The calculated wind field and the corresponding pollutant mass distribution are presented and discussed in connection with the experimental remote sensing data.
