Hi Kevin,

I would advise to have at our disposal:

- A climatological record for your ROI of at least 5 years;

- A DTM of high resolution, to enable the estimation of turbulence at ground level.

- At the same time a map of roughness length at the same scale as the DTM (can be derived from the DTM and Climatology.

- Based on these data you can calculate footprints of the tower (and its required height) in function of its position. You can look at the position where your footprint is most stable and covers your ROI optimally as well. Optimal means here coverage of your vegetation type under study as homogeneously as possible.

- Homogeneity (or better even heterogeneity) of vegetation can be calculated according to methodology described in a paper of Balzarolo et al. to be found here at ResearchGate:

Article Influence of Landscape Heterogeneity and Spatial Resolution ...

Cheers,

Good question.
