L: Latent heat flux density (W / m^2)

L: Latent heat flux density (W / m^2)

.get_L(T_leaf, pars, unitless)

Arguments

T_leaf	Leaf temperature in Kelvin
pars	Concatenated parameters (leaf_par, enviro_par, and constants)
unitless	Logical. Should function use parameters with units? The function is faster when FALSE, but input must be in correct units or else results will be incorrect without any warning.

Value

Value in W / m^2 of class units

Details

$$L = h_\mathrm{vap} g_\mathrm{tw} d_\mathrm{wv}$$

Symbol	R	Description	Units	Default
\(d_\mathrm{wv}\)	d_wv	water vapour gradient	mol / m ^ 3	calculated
\(h_\mathrm{vap}\)	h_vap	latent heat of vaporization	J / mol	calculated
\(g_\mathrm{tw}\)	g_tw	total conductance to H2O	(\(\mu\)mol H2O) / (m\(^2\) s Pa)	calculated

Examples

library(tealeaves)

cs <- make_constants()
ep <- make_enviropar()
lp <- make_leafpar()

T_leaf <- set_units(298.15, K)

tealeaves:::.get_L(T_leaf, c(cs, ep, lp), FALSE)
