Code 12.5: ZRT Emission Model for Vegetation

Code Name: ZRTemission_Veg.m

Description: Code computes emissivity of a vegetation layer above a soil surface.

Input Variables:

ε = ε^' - jε^'':	Soil dielectric constant (unitless)
Θ₁:	Incidence angle (degrees)
f:	Frequency (GHz)
s:	rms height of soil surface (m)
l:	Correlation length of soil surface (m)
a:	Single-scattering albedo (unitless)
κ_e:	Extinction coefficient of vegetation layer (Np/m)
d:	depth of vegetation layer (m)

Output Products:

e^h(Θ₁):	h-polarized emissivity (unitless)
e^v(Θ₁):	v-polarized emissivity (unitless)
