This module computes the
optical thickness under cloudy conditions for an atmospheric layer
between heights
z1 and
z2,
containing a cloud layer extending between
z3 and
z4,
for propagation along
direction θ
relative to the zenith (0 < θ < 80
o) at any frequency 0 < f < 1000 GHz,
using a Standard Atmosphere model.
It is assumed that the cloud
layer is partially or totally within the atmospheric layer of interest
(
z1 and
z2).
