In serbinsh/R-PROSPECT: R functions for running PROSPECT family of leaf radiative transfer models

Description

Invert the PROSPECT family (PROSPECT-4,PROSPECT-5,PROSPECT-5B) of leaf radiative transfer models

Usage

  invprospect(refl, tran, model, method, strategy,
    threshold, cpus, type)

Arguments

refl	observed leaf reflectance data
tran	observed leaf transmittance data
model	version of PROSPECT model to invert. Options: 4,5,5B. Default = 4
method	algorithm for finding the minimum of cost function between observed and modeled spectra (i.e. optimize the model parameters). Current options: DEoptim
strategy	DEoptim strategy (see DEoptim)
threshold	minimum threshold of the difference between observed and modeled spectra during optimization. Default = 0.0001
cpus	the number of cpus to use in parallel inversion of PROSPECT (optional)
type	the type of cluster to run the parallel inversion. Options: 'SOCK','MPI'. Default: 'SOCK'. Also see ?snowfall

Details

Function to invert the PROSPECT family (PROSPECT-4,PROSPECT-5,PROSPECT-5B) of leaf radiative transfer models (RTMs) on measured reflectance and transmittance data. This function is used for single spectra inversions.

Value

output optimum set of leaf parameters (N,Cab,Car,Cbrown,Cw,Cm), rmse of the inversion, and associated modeled reflectance and transmittance
