Surface Roughness from Empirical Measurements

Description

The function estimates surface roughness (m) from empirical wind speed (m s^-1) data collected at a vector of heights (m) \insertCiteKingsolver2015,Campbell1998,Porter1979TrenchR.

Usage

surface_roughness(u_r, zr)

Arguments

u_r	numeric wind velocity (m s-1) at a vector of reference heights.
zr	numeric vector of reference heights (m).

Value
