Short description

The vision of future cities is to combine sustainability and greenery with dense populations. To achieve a good outdoor air environment it is crucial to understand how vegetation, denser building construction and the traffic situation affect air quality. We will create sophisticated modelling tools to analyse urban air quality with respect to vegetation, buildings and traffic.

The CityAirSim project also has the ambition to create an interactive digital tool where the user can experience the city environment through virtual reality (VR) and explore how the air is affected by placing buildings, vegetation and roads in different locations. Field measurements, model development and scenario simulations are some of the foundation work carried out to produce the VR tool.

The project combines knowledge from biology and meteorology with pedagogy and visualisation. The tool and results are expected to be used by teachers/students and decision makers in education and urban planning.
