The project aims to determine the impact of current green infrastructure on temperature and air quality in selected European cities. The model-based investigation includes scenario analyses regarding plant species selection and green space distribution in order to optimize climate and air quality under current and future conditions. Sensitivity analysis, in particular regarding BVOC emission, will be carried out to quantify the uncertainty in model simulations and methodological improvements will be suggested.
Therefore, the iTree-eco model (https://www.itreetools.org/eco/) will be used, which has been developed by public bodies in the US for evaluating urban green ecosystem services. The model calculates the impact on carbon sequestration, shading and pollution removal in dependence on tree species distribution, weather and air pollution concentration data. Detailed tree and environmental data for initializing the model and running the simulations for a major park in Munich and whole of Berlin have already beeing gathered from installed measurement networks and cooperation partners.
