Abstract
AbstractThe urban canopy scheme DCEP coupled with the mesoscale climate model COSMO‐CLM is evaluated extensively against data from the Basel Urban Boundary Layer Experiment (BUBBLE) for the period 20 June 2002 to 10 July 2002. The urban canopy parameters required for this purpose are based on a 3D building dataset of the canton of Basel‐Stadt (Switzerland) and land‐use data for Basel and its surroundings. The simulated radiative and energy fluxes as well as near‐surface air temperatures and wind velocities are compared with the measurements. The results indicate a good online performance of the model system which is comparable with the offline performance of other urban canopy schemes in terms of the fluxes. DCEP is able to simulate typical characteristics of the urban boundary layer, in contrast to the default bulk‐transfer scheme of COSMO‐CLM.
