The DPRA Heat stress report indicates on page 31 that the area directly below trees and bushes should be excluded from the average Sky View calculation used for the Urban Heat Island (UHI) effect. However it is still included in the PET according to the result images on page 101, the sky view is assumed to be zero here.
