boundary_layer_resistance: Boundary Layer Resistance

In TrenchR: Tools for Microclimate and Biophysical Ecology

Boundary Layer Resistance

Description

The function estimates boundary layer resistance under free convection based on the function in \insertCiteRiddell2018;textualTrenchR.

Usage

boundary_layer_resistance(T_a, e_s, e_a, elev, D, u = NA)

Arguments

T_a	numeric air temperature (K).
e_s	numeric saturation vapor pressure (kPa).
e_a	numeric actual vapor pressure (kPa).
elev	numeric elevation (m).
D	numeric characteristic dimension (e.g., body diameter) (m).
u	numeric wind speed (m s-1), if not provided assume free convection; if provided, use forced convection if appropriate.

Value

numeric boundary layer resistance (s cm^-1).
