摘要

Aim of this research is to determine capabilities of vegetated areas and open areas in the inner city of Dresden to attenuate microclimatic extremes. The study is embedded in the project "city nature and open area structures under climate change" of the German Federal Agency for Nature Conservation. The diversity of impacts of different urban areas on the microclimate is presented by mobile measurements and model simulations. Simulations were carried out with the coupled vegetation-boundary layer model HIRVAC-2D and the 3D microclimate model ENVImet. Model output agrees quite well with measurements of air temperature on sunny days in the year 2009. E. g., the maximum temperature difference between high and dense vegetation areas and the sealed and built city surrounding reaches up to 4 K at a hot and sunny summer day.
