Short summary
This work presents an investigation into varying modelling choices for large-eddy simulation over realistic forests. The focus is on how to represent the impact of upstream forest cover on wind statistics. The work clearly demonstrates the advantage of using an explicit drag formulation together with forest density maps from airborne laser scans over using roughness length and displacement height, mainly because it leverages observable quantities and minimizes the impact uncertain choices.
