E: Evaporation (mol / (m^2 s))

ER Documentation

Evaporation (mol / (m^2 s))

Description

Evaporation (mol / (m^2 s))

Usage

E(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.

Details

The leaf evaporation rate is the product of the total conductance to water vapour (m / s) and the water vapour gradient (mol / m^3):

E = g_tw D_wv

If unitless = TRUE, T_leaf is assumed in degrees K without checking.

Value

unitless = TRUE: A value in units of mol / (m ^ 2 / s) number of class numeric unitless = FALSE: A value in units of mol / (m ^ 2 / s) of class units

Examples


library(tealeaves)

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

T_leaf <- set_units(298.15, K)

E(T_leaf, c(cs, ep, lp), FALSE)
