Ground Level Temperatures Before and After the Intervention

Data on ground level temperature can be collected from weather stations. When using weather station data, it is important to make sure that the station is properly calibrated. Most weather stations come with instructions on how to do this. Once the station is calibrated, readings can be collected from the “outside” temperature sensor, which can be used as the ground level temperature. It is advisable to take multiple readings over a period of time to get an accurate average, as this will provide the best data on ground level temperature.²

Urban green space cooling effect in cities

Aram et al. (2019) conducted a systematic review of research studies on how improved urban green spaces create a cooling effect and reduce the ground level temperature. The review searched for articles that critically discussed the relationship between reduced ground level temperature and urban green spaces. From this study, it was deduced that urban green spaces with an area of 0.5-2 hectares can only reduce the temperature by up to 0.3 °C over a distance of 40 m, whereas those with an area of 3-5 hectares may reduce it by up to 0.7 °C over a distance of 70–120 m.
