This module computes the
emissivity of a homogeneous medium with a rough surface,
using the parametric model equations
developed by Lawrence et al. (2013).
Model is applicable to L-band only.
Various parameters of the rough surface can be specified, such as the
dielectric constant
ϵ =
ϵ' -j
ϵ'',
the rms height and the correlation length.
The model is constrained to realistic surfaces with
( rms height / correlation length ) ≤ 0.25.
