Create a parameterisation function

function ParamViz.parameterisation(PAR, LAI, ρ_leaf, K, Ω, a, b)   
         APAR = PAR * (1 - ρ_leaf) * (1 - exp(-K * LAI * Ω)) 
         return APAR
end

Create struct

    drivers = Drivers(("PAR (μmol m⁻² s⁻¹)", "LAI (m² m⁻²)"),
                         (FT.([0, 1500 * 1e-6]), FT.([0, 10])),
                         ((mol*m^-2*s^-1, μmol*m^-2*s^-1), (m^2*m^-2, m^2*m^-2))
                        )

    parameters = Parameters(("canopy reflectance, ρ_leaf",
                                "extinction coefficient, K",
                                "clumping index, Ω"),
                               (FT.([0, 1]), FT.([0, 1]), FT.([0, 1])),
                               ((m, m), (m, m), (m, m)) # dummy units, no conversion
                              )

    constants = Constants(("a", "b"), (FT(1), FT(2))) # dummy constants
    inputs = Inputs(drivers, parameters, constants)
    output = Output("APAR (μmol m⁻² s⁻¹)", [0, 1500 * 1e-6], (mol*m^-2*s^-1, μmol*m^-2*s^-1))
