Differences between the temperature of vegetated urban parks and that of their surrounding built environment are reported. The study is based on observations of surface and air temperature in Vancouver, BC and Sacramento, CA. during summer conditions. A combination of remotely sensed surface temperature and air temperature from fixed station and mobile (car and bicycle) traverses is used to characterize the magnitude of park-induced coolness the 'park cool island' (PCI) effect. Relatively large surface PCI are present by day and at night, although for different reasons.
