Investigation of the urban climate, and especially that of the urban heat island (UHI) phenomenon, still faces new challenges. Even with increasing computational capabilities and geographic information systems (GIS), there is a need for standardized research methods. Furthermore, research output should be applicable in practise. Microscale meteorological and climate models have been increasingly used for simulations of real urban city environments and especially the impacts of changes in the city structure on the environmental conditions that affect the inhabitants. In this context, various UHI mitigation measures are being considered, with greening of the environment as a typical example. Application of these measures, however, needs some prior information about their potential effectiveness or a cost-benefit analysis. For that, it is important to know how sensitive the environment is to the city layout (e.g., building height or street width) and the material-specific parameters used to describe urban surfaces (e.g., reflectivity or roughness). Currently, the demand for scientifically-based urban climate studies is growing, particularly model-based studies that can provide reliable projections on a city or street-level scale.
