To improve prediction of the meteorological fields inside the street canyon with TEB, a new version has been developed, following the methodology described in a companion paper (Masson et al. 2009). It resolves the surface boundary layer inside and above urban canopy by introducing a drag force approach. This new version is tested offline in a street canyon. Results are compared with the original singlelayer version of TEB and with measurements within and above the street canyon. Results show that this new version produces profiles of wind speed, friction velocity, turbulent kinetic energy, turbulent heat flux, and potential temperature that are more consistent with observations. Furthermore, this new version can still be easily coupled to mesoscale meteorological models.
