Tb_snail: Operative Environmental Temperature of a Marine Snail

In trenchproject/TrenchR: Tools for Microclimate and Biophysical Ecology

Operative Environmental Temperature of a Marine Snail

Description

The function estimates body temperature (C, operative environmental temperature) of a marine snail. The function implements a steady-state model, which assumes unchanging environmental conditions and is based on \insertCiteIacarella2012TrenchR. Body temperature and desiccation constrain the activity of Littoraria irrorata within the Spartina alterniflora canopy. The function was provided by Brian Helmuth and is a simplified version of the published model.

Usage

Tb_snail(temp, l, S, u, CC, WL, WSH)

Arguments

temp	numeric air temperature (C).
l	numeric snail length (m).
S	numeric direct solar flux density (W m-2).
u	numeric wind speed (m s-1).
CC	numeric fraction of the sky covered by cloud (0-1).
WL	numeric water loss rate (kg s-1), 5 percent loss of body mass over one hour is a reasonable maximum level \insertCiteHelmuth1999TrenchR.
WSH	numeric wind sensor height (m).

Details

Thermal radiative flux is calculated following \insertCiteHelmuth1998;textualTrenchR, \insertCiteHelmuth1999;textualTrenchR, and \insertCiteIdso1969;textualTrenchR.

Value

numeric predicted body (operative environmental) temperature (C).
