Abstract

Green infrastructure is the cooling hub of the built environment in urban settings. These interactions could contribute towards the reduction of the rise in temperature due to urban heat island effects. It is common practice to evaluate the cooling extent using onsite observations. Alternatively, satellite data could be a possible source to perform the former. We analyse and evaluate the extent using the satellite observations. Intuitively, as we go further from a park, the cooling effect will decrease but this need to be quantified. We analyse Landsat-8 images to generate a temperature distribution in urban environment. The Land Surface Temperature (LST) was derived from Landsat-8 and downscaled from 30 m to 10 m using the Sentinel-2 spectral indices in the Greater London area. This gives a relatively high resolution LST variation in urban environment. A profile over a park was extracted to observe the extent of cooling from the green infrastructure extends towards the build environment. The cooling effect varies with the park and the effect extends up to 300 m. These observations contribute towards the urban planners to maximise the cooling benefits of urban parks to promote urban resilience and sustainability.
