air_temp_profile_segment: Air Temperature at a Specified Height

In trenchproject/TrenchR: Tools for Microclimate and Biophysical Ecology

Air Temperature at a Specified Height

Description

The function calculates air temperature (C) at a specified height (m). 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

air_temp_profile_segment(T_r, u_r, zr, z0, z, T_s)

Arguments

T_r	numeric a vector of air temperatures (C) at the 3 reference heights.
u_r	numeric a vector of wind speeds (m s-1) at the 3 reference heights.
zr	numeric a vector of 3 reference heights (meters).
z0	numeric a vector of 3 experimentally determined roughness heights (meters).
z	numeric height for air temperature estimation (meters).
T_s	numeric surface temperatures (C).

Value

numeric air temperature (C).
