A detailed analysis of the urban heat island and heatstress dynamics was performed for the city of Ghent, Belgium. In the summer of 2012, an experimental measurement campaign was conducted with various fixed sampling locations (both own as well as thrid-party e.g. coming from hobbyists) and mobile transects. The surface heat island (SUHI) was visualised and analysed based upon remote sensing LST retrievals from ASTER/Landsat. These maps were further translates into an estimated level of potential heat stress during the day. Next, the canopy layer heat island was studied in addition by UrbClim model runs. A subcontractor, University of Ghent (dep. spatial planning) was responsible for detecting the causes of the UHI in Ghent and performing a vulnerability analysis w.r.t. heat stress in the city. Complemented with a number of scenario runs taking into account changing climate conditions and land use projections (2030), the projects results were translated into policy-relevant information.
