Working focus

The goal of the research is to understand interactions between urban structure and urban climate, as well as to quantify the impacts on urban residents. Processes on different spatial and temporal scales are investigated: from the interaction of individual vegetation elements with the environment in the diurnal cycle to the climatological heat island effect of the entire city. The following are the focal points:

• Measurement and model simulation of the effects of urban structures on the thermal well-being of urban residents
• Assessments of thermal stress in urban neighborhoods considering different climate change adaptation measures
• Quantification of the effects of urban green
• Measurement and modeling of the propagation of sound, particles and gaseous substances
• Studies on the influence of urban surface properties on flow and thermodynamics
• Investigation of cold air development and flow
• Modeling precipitation amplification due to the urban heat island effect

Tools

• Stationary and mobile measurement systems

• Models: Micro-scale: PALM-4U, ENVI-met, SOLWEIG, meso-scale: WRF
