By providing a data interface, it is possible to use the data from the Digital Twin Munich for air pollution simulations.
The Digital Twin Munich provides centralized and user-friendly access to all relevant specialist data for the spatial modelling of air pollutant distribution. This data ranges from traffic flows and pollutant measurements from the official measuring stations of the Bavarian Environment Agency (LfU) to 3D building structures. By evaluating this data, the Digital Twin Munich can provide valuable insights that contribute to a better understanding of air quality in the urban area. Therefore, an interface was developed in the funding project DT-M that enables requirement-oriented data export for common types of air pollutant models. A central challenge in the context of air pollution modeling is the selection and preparation of very heterogeneous data sets. By using the interface, the municipal department is able to prepare the input data required for air quality model simulations both efficiently and reproducibly.
