Code 12.3: L-Band Semiempirical Emissivity Model for Rough Surface

Code Name: SemiEmp_EmissivityModel_RoughSurf.m

Description: Code computes polarized emissivities for a random surface using the parametric model equations developed by Lawrence et al. (2013).

Input Variables:

ε = ε^' - jε^'':	Dielectric constant of the surface (unitless)
s:	rms height (m)
l:	correlation length (m)
Θ:	Incidence angle (degrees)

Output Products:

e^h(Θ):	h-polarized emissivity (unitless)
e^v(Θ):	v-polarized emissivity (unitless)
