Urban climate under change

Urban areas react highly sensitively to changes in climate, such as extended heat periods, severe storms or floods. The consequence: cities must already prepare themselves for climate change. In that respect cities are a special place of conflict, for example between the rising pressure on settlements on the one hand, and the necessary adaptations to the consequences of climate change on the other.

The basis for the necessary planning decisions in cities are powerful city climate models. So far, however, such models which are able to make clearly defined statements on climate changes and urban climatological contexts are lacking.
As part of the "Urban Climate Under Change [UC]²" project, a new, innovative city climate model is to be developed. The model will be able to simulate atmospheric processes on a building level. In this way, interdisciplinary analyzes can be carried out and measures for the improvement of the city climate and air pollution can be planned.

"Urban climate under change" is thus faced with the challenge of giving cities and urban regions a scientifically sound and effective tool to tackle the problems associated with present and future climatic conditions and air pollution. The funding measure began on 1 June 2016 and will be financed by BMBF for three years. The work is organized in three modules devoted to the aspects of model development, evaluation, and usability. Within the three modules (A, B, C) four composite projects (MOSAIK, 3DO, KliMoPrax and UseUClim) work together with a total of 30 subprojects.
