Local impact of tree volume on nocturnal urban heat island

A case study in Amsterdam

The aim of this research is to quantify the local impacts of tree volumes on the nocturnal urban heat island intensity (UHI). Volume of each individual tree is estimated through a 3D tree model dataset derived from LIDAR data and modelled with geospatial technology. Air temperature is measured on 103 different locations of the city on a relatively warm summer night. The results of this study indicate that, in our case study area, tree volume has the highest impact on UHI within 40 m and that a one degree temperature reduction is predicted for an increase of 60,000 m3 tree canopy volume in this 40 m buffer.
