wind_speed_profile_segment {TrenchR} | R Documentation |
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 Kearney and Porter (2017).
