wind_speed_profile_segment: Wind Speed at a Specified Height

In TrenchR: Tools for Microclimate and Biophysical Ecology

Wind Speed at a Specified Height

Description

The function calculates wind speed (m s^-1) at a specified height (m). The function estimates a three segment velocity and temperature profile based on user-specified, experimentally determined values for 3 roughness heights and reference heights. Multiple heights are appropriate in heterogenous areas with, for example, a meadow, bushes, and rocks. Implements the MICROSEGMT routine from NicheMapR as described in \insertCiteKearney2017;textualTrenchR.

Usage

wind_speed_profile_segment(u_r, zr, z0, z)

Arguments

u_r	numeric a vector of wind speeds (m s-1) at the 3 reference heights.
zr	numeric a vector of 3 reference heights (m).
z0	numeric a vector of 3 experimentally determined roughness heights (m).
z	numeric height to scale (m).

Value

numeric wind speed (m s^-1).
