This study presents a multi-stage approach to quantify the cooling effect of urban parks in the metropolitan region of Barcelona from the Land Surface Temperature (LST) of Landsat-8 of a summer day. We quantified the cooling extent (Lmax) and intensity (¿T) of seven parks in the conurbation of Viladecans, Gavà and Castelldefels thorugh three analytical methods based on a multi-stage spatial subdivision of the urban surroundings. First results show ¿T of 1.25°C and 1.50°C in relation to the 0-100m and 100-300m concentric urban annuli respectively. The Lmax calculated by 10m-width concentric annuli registered 91.67m average with ¿T of 1.22°C. Last, 10m-width transversal sections to the park resulted in average ¿T of 2.21°C in industrial zones, 1.05°C in residential areas and 1.76°C adjacent to another park. Where the Lmax resulted in 109.00m average to northeast and 129.67m to southwest, with maximum 170m in the industrial zone and 310m in the another park’s area respectively. Conclusions discuss differences between methods applied and considerations to further replication in larger scale studies.
