energy_balance: Calculate leaf energy balance

Description

Calculate leaf energy balance

Usage

energy_balance(
  tleaf,
  leaf_par,
  enviro_par,
  constants,
  quiet = FALSE,
  components = FALSE,
  set_units = FALSE
)

Value

A numeric value in W / m^2. Optionally, a named list of energy balance components in W / m^2 and transpiration in mol / (m^2 s).

Arguments

tleaf

Leaf temperature in Kelvin. If input is numeric, it will be automatically converted to units.

leaf_par

A list of leaf parameters. This can be generated using the make_leafpar function.

enviro_par

A list of environmental parameters. This can be generated using the make_enviropar function.

constants

A list of physical constants. This can be generated using the make_constants function.

quiet

Logical. Should a message appear about conversion from numeric to units? Useful for finding leaf temperature that balances heat transfer using uniroot.

components

Logical. Should leaf energy components be returned? Transpiration (in mol / (m^2 s)) also returned.

set_units

Logical. Should units be set? The function is faster when FALSE, but input must be in correct units or else results will be incorrect without any warning.

Examples

library(tealeaves)

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

T_leaf <- set_units(298.15, K)

energy_balance(T_leaf, lp, ep, cs, FALSE, TRUE, TRUE)
