In TrenchR: Tools for Microclimate and Biophysical Ecology

Operative Environmental Temperature of an Ectotherm Based on a Variant of Gates (1980)

Description

The function predicts body temperatures (C, operative environmental temperature) of an ectotherm using the approximation in \insertCiteGates1980;textualTrenchR. The function omits evaporative and metabolic heat loss.

Usage

Tb_Gates2(A, D, T_g, T_a, Qabs, u, epsilon)

Arguments

A	numeric surface area (m2).
D	numeric characteristic dimension for conduction (meters).
T_g	numeric ground surface temperature (C).
T_a	numeric ambient air temperature (C).
Qabs	numeric Solar radiation absorbed (W).
u	numeric Wind speed (m s-1).
epsilon	numeric longwave infrared emissivity of skin (proportion), 0.95 to 1 for most animals \insertCiteGates1980TrenchR.

Value

numeric operative environmental temperature (C).
