Stockholm Heat II

As our cities are getting hotter due to climate change, high-resolution thermal data can be used to study urban heat patterns and trends related to urban form and greenery to support urban planners in designing mitigation strategies and help citizens make informed decisions about their whereabouts.

Since 2021, the Stockholm Heat project has been mapping air temperature, humidity, and radiant temperature of urban surfaces in central Stockholm using an opportunistic fleet of low-cost sensors (City Scanners) mounted on electric tuk-tuks, collecting over 2M data points.

Building on the methodology and the data we developed in the first chapter of this project, we want to study further the impact of urban form and greenery on urban heat islands in order to measure the role of urban greenery to mitigate extreme heat at the hyperlocal scale.

The project will entail the deployment of an improved version of the City Scanner to capture high-resolution, semantically rich thermal data using privacy-preserving edge AI algorithms. In addition, the project will make use of the detailed Stockholm City data on trees, biotopes and buildings to provide relevant information on urban planning and climate adaptation of sustainable cities.
