are presented in the same table.
As is seen fromthe table, the uncertainty in the case of inhomogeneous layers
is the same as in the case of the homogeneous layers and depends only on the
applicability region of the used equations (magnitudes of the single scattering
albedo and optical thickness). The high values of the uncertainties appear only
for the high absorbing sublayers with values of the single scattering albedo

calculation (Fig. 2.2) and for the retrieved parameters (Fig. 6.5).
