fourSAIL model coupled with several leaf models

foursail.Rd

foursail fourSAIL simulation based on a set of combinations of input parameters

Usage

foursail(inputLUT, rsoil, LeafModel = "PROSPECT-PRO", spectrum.all = T)

Arguments

inputLUT

LUT table with distribution of biophysical parameters used as input parameters in the model

rsoil

numeric. Soil reflectance

LeafModel

Version of PROSPECT model, Liberty model and fluspect model. For PROSPECT model: 'PROSPECT-PRO' or 'PROSPECT-D' is accepted. By default 'PROSPECT-PRO' is used. fluspect model is valid in two options: 'Fluspect-B' and 'Fluspect-B-Cx'. Liberty as 'Liberty'

spectrum.all

a boolean value, False is for SPART and Fluspect Models (400-2400 nm), True for the PROSPECT and Liberty models (400-2500 nm) Liberty model is leaf radiative transfer model designed for conifer needles. Uses 'Liberty' Fluspect-B model is leaf radiative transfer model designed for adding fluorescence emission. Uses 'Fluspect-B' or 'Fluspect-B-Cx'.

Value

list. rdot,rsot,rddt,rsdt

rdot: hemispherical-directional reflectance factor in viewing direction rsot: bi-directional reflectance factor rsdt: directional-hemispherical reflectance factor for solar incident flux rddt: bi-hemispherical reflectance factor
