log_wind_profile: Estimates wind speed at height z2 based on wind speed measued...

In jvitorpinto/agmet: Utilities for agricultural meteorology

Estimates wind speed at height z2 based on wind speed measued at height z1, given the height of the zero plane displacement and the roughness length of the surface.

Description

For a standardized FAO Peman Monteith ET0 surface you can use the default values for d and z0. If the wind speed is measured at a standard weather station, which measures wind speed at a 10m height, you can use the default value for z1.

Usage

log_wind_profile(u1, z2 = 2, z1 = 10, d = 0.084, z0 = 0.01476)

Arguments

u1	Wind speed [m/s] measured at height z1.
z2	Height z2 [m].
z1	Height z1 [m]. The default is 10.
d	Zero plane displacement height. If not set, a default value = 0.08 will be set, which is the zero plane displacement height estimated for a 0.12m height uniform crop.
z0	Roughness length. If not set, a default value of 0.01476 will be set, which corresponds to the roughness length of the standardized FAO ET0 Penman-Monteith equation.

Value

Wind speed at height z2.
