get.RTMf.Rd

get.RTMf get.RTMf Calculates the spectrum of fluorescent radiance in the observer's direction and also the TOC spectral hemispherical upward Fs flux.

Usage

get.RTMf(
  data.spectral,
  data.rad,
  data.soil,
  data.leafopt,
  data.canopy,
  data.gap,
  data.angles,
  data.etau,
  data.etah,
  get.plots = T
)

Arguments

data.spectral

information about wavelengths and resolutions

data.rad

a large number of radiative fluxes: spectrally distributed and integrated, and canopy radiative transfer coefficients.

data.soil

soil properties

data.leafopt

leaf optical properties

data.canopy

canopy properties (such as LAI and height)

data.gap

probabilities of direct light penetration and viewing

data.angles

viewing and observation angles

data.etau

relative fluorescence emission efficiency for sunlit leaves

data.etah

relative fluorescence emission efficiency for shaded leaves

get.plots

logical. If TRUE, intermediate diagnostic plots are produced. Default TRUE.

Value

a rad object with a large number of radiative fluxes: spectrally distributed and integrated, and canopy radiative transfer coefficients.

Details

Date: 12 Dec 2007. Update history:

  • 26 Aug 2008 CvdT small correction to matrices

  • 07 Nov 2008 CvdT changed layout

  • 19 Mar 2009 CvdT major corrections: lines 95-96,101-107, and 119-120.

  • 07 Apr 2009 WV & CvdT major correction: lines 89-90, azimuth dependence was not there in previous verions (implicit assumption of azimuth(solar-viewing) = 0). This has been corrected

  • May-June 2012 WV & CvdT Add calculation of hemispherical Fs fluxes

  • Jan-Feb 2013 WV Inputs and outputs via structures for SCOPE Version 1.40

  • Aug-Oct 2016 PY Re-write the calculation of emitted SIF of each layer. It doesnt use loop at all. with the function bsxfun, the calculation is much faster

  • Oct 2017-Feb 2018 PY Re-write the RTM of fluorescence

  • Jan 2020 CvdT Modified to include 'lite' option, mSCOPE representation

  • 25 Jun 2020 PY Po, Ps, Pso. fix the problem we have with the oblique angles above 80 degrees
