Citizair – visualize air data

In the CitizAir project, KTH, SLB-analys and Science & Public are working together with the Stockholmers to make air data visible. On their mobiles, screens and on light boards around the city, residents should be able to see which route through the city has the best air quality. The goal of CitizAir is to create an interactive augmented reality, which connects up-to-date air data and information screens in the urban environment with an app in Stockholmers’ mobile phones.

The residents of Stockholm, together with other stakeholders, researchers at KTH and SLB-analys, will be involved in designing the new visualization tool. An important point of departure for the project is to start from Stockholmers’ views, knowledge and needs. The project started at the end of 2021 and in 2024 it will be possible to see the quality of Stockholm’s air on interactive screens.

The two air pollutants that affect Stockholmers’ health the most are nitrogen dioxide and microparticles (PM10, particles whose diameter is less than 10 micrometers). Therefore, the levels of these pollutants should be shown and visualized locally, where the levels are measured.

It should be possible to interact with the information screens and download data from them to your mobile phone. In this way, Stockholmers can make informed decisions about which route to take or which mode of transport they should choose. In the long run, they will also be better equipped to be able to discuss and themselves influence decisions and policies relating to the environment and urban planning.

Everything that is developed within CitizAir will be published openly and be possible to use in other cities and parts of the world. In this way, the project contributes to the sustainable development of cities and urban life and to several of the global sustainability goals.

The project is financed by the research council Formas.
