Greenery cools down city by 0.6°C in Antwerp
At the mesoscale, an increase from approximately 20-30% to 60% vegetation cover in the city lowers the temperatures by around 0.6°C in Antwerp. Therefore, greening the city does have an impact on the UHI, but only to a limited extent, unless the urban roughness length is also reduced. More details can be found in the report “Urban adaptation effects on urban climate”.
