In ashiklom/fortebaseline: Forest Resilience and Threshold Experiment (FoRTE) ED2 baseline runs source code and manuscript

Description

R implementation of ED2 two-stream radiation model

Usage

two_stream(
  ipft,
  L,
  lr,
  lt,
  orient,
  cai = rep(1, length(L)),
  theta = 15,
  S0_beam = 0.8,
  S0_diff = 1 - S0_beam,
  alb_ground = 0.1
)

Arguments

cai	Crown area of each cohort (ncoh)
czen	Cosine of angle of incidence ('cosaio')
iota_g	Ground (soil + snow) albedo
pft	PFT identities of each cohort, as integer (ncoh)
lai	Leaf area index of each cohort (ncoh)
wai	Wood area index of each cohort (ncoh)
orient_factor	Orient factor (npft)
clumping_factor	Clumping factor (npft)
leaf_reflect	Leaf reflectance spectra (nwl * npft)
leaf_trans	Leaf transmittance spectra (nwl * npft)
wood_reflect	Wood reflectance spectra (nwl * npft)
wood_trans	Wood transmittance spectra (nwl * npft)
down_sky	Normalized diffuse solar spectrum (nwl)
down0_sky	Normalized direct solar spectrum (nwl)
wavelengths	Numeric vector of wavelengths to use, in nm (nwl). Default is 400:2500.
