gpm: Generalized plate model

In ashiklom/rrtm: Implementations of radiative transfer models in R

Generalized plate model

Description

Generalized plate model

Usage

gpm(k, N, talf, t12, t21, e1fun = e1_approx)

Arguments

k	Optical depth (numeric(nwl))
N	Effective number of leaf layers (numeric(1))
talf, t12, t21	Pre-calculated quantities based on refractive index and angle
e1fun	Function to use for exponential integral. Default is e1_approx, included here. For greater precision, use gsl::expint_E1.

Value

A length-2 list containing the modeled reflectance and transmittance
