PlantBiophysics provides reusable model kernels for leaf-scale biophysics:

  • light interception;
  • photosynthesis;
  • stomatal conductance;
  • energy balance.

The models run through PlantSimEngine's scene/object API and can be reused in single-leaf, multi-organ, multi-plant, soil, and microclimate simulations.

Quick Start

using PlantBiophysics, PlantSimEngine, PlantMeteo, Dates

meteo = Atmosphere(
    T=22.0,
    Wind=0.8333,
    P=101.325,
    Rh=0.45,
    duration=Hour(1),
)

scene = leaf_scene(
    Monteith(),
    Fvcb(),
    Medlyn(0.03, 12.0);
    status=Status(
        Ra_SW_f=13.747,
        sky_fraction=1.0,
        aPPFD=1500.0,
        d=0.03,
    ),
    environment=meteo,
)

simulation = run!(scene)
leaf = only(model_objects(scene; scale=:Leaf))
(Tₗ=leaf.status.Tₗ, A=leaf.status.A, Gₛ=leaf.status.Gₛ)
(Tₗ = 18.003618476920586, A = 32.010730315098684, Gₛ = 1.3459773860136361)

leaf_scene creates one :Leaf object and one model application per supplied kernel. Hard dependencies remain explicit: Monteith calls photosynthesis, and coupled photosynthesis models call stomatal conductance.
