Answer to (3): The TEB model used in this study is a single model with all the
exchanges (of heat, momentum and chemical species) between the urban canopy
and atmosphere occurring at the last model level. The scheme proposed by Martilli
et al. can handle exchanges at several model levels. It may provide a better way
describing the spatial distribution of air pollutants in urban areas particularly in the
downtown core with high density of high-rise buildings.
