Description

This function uses optimal configuration identified by Spafford et al. (2020) to estimate leaf chemistry prior information on N is provided if only Reflectance or only Transmittance is available

Usage

Invert_PROSPECT_OPT(
  lambda,
  SpecPROSPECT = NULL,
  Refl = NULL,
  Tran = NULL,
  MeritFunction = "Merit_PROSPECT_RMSE",
  PROSPECT_version = "D",
  Parms2Estimate = "ALL",
  InitValues = data.frame(CHL = 40, CAR = 10, ANT = 0.1, BROWN = 0.01, EWT = 0.01, LMA =
    0.01, PROT = 0.001, CBC = 0.009, N = 1.5, alpha = 40),
  xlub = data.frame(CHL = c(1e-04, 150), CAR = c(1e-04, 25), ANT = c(0, 50), BROWN = c(0,
    4), EWT = c(1e-08, 0.1), LMA = c(1e-06, 0.06), PROT = c(1e-07, 0.006), CBC = c(1e-06,

Arguments

lambda	numeric. spectral bands corresponding to experimental data
SpecPROSPECT	list. Includes optical constants refractive index, specific absorption coefficients and corresponding spectral bands
Refl	numeric. Measured reflectance data
Tran	numeric. Measured Transmittance data
MeritFunction	character. name of the function to be used as merit function
PROSPECT_version	character. Version of prospect model used for the inversion: 'D', 'PRO'.
Parms2Estimate	character vector. Parameters to estimate (can be 'ALL')
InitValues	data.frame. Default values of PROSPECT parameters. During optimization,
xlub	data.frame. Boundaries of the parameters to estimate. The data.frame must have columns corresponding to Parms2Estimate first line being the lower boundaries and second line the upper boundaries.
verbose	boolean. set to TRUE to display sample number to be inverted they are used either as initialization values for parameters to estimate, or as fix values for other parameters. Parameters not compatible with PROSPECT_version are not taken into account.
progressBar	boolean. show progressbar?

Value

Nprior vector corresponding to teh prior estimation of N based on R only or T only
