Such a data set will allow us to investigate the key parameters for urban dispersion modeling, namely, the ‘surface‘ momentum flux (profile), the ‘surface‘ heat flux (profile), the mixing height and associated scaling velocities, the profiles of mean wind speed and velocity variances throughout the urban boundary layer. For some of the mentioned variables, some data already exists and the project will contribute to extend the range of surfaces (roughness characteristics and density) studied so far. For others, nothing is presently available (e.g., the profile of sensible and latent heat flux within the urban RS) and the data will help to establish first attempts for parameterizations.
The project will further give us the opportunity to show the feasibility of using the wind profiler technique for urban wind climatology, in combination with LIDAR data for determining the boundary layer height, and as a tool for the meteorological surveillance of installations with high hazard potential such as chemical and nuclear plants.
