to the a priori ones, so it is better to discuss the correct accounting of the
a priori indefinites of their content assignments but not the results of the
vertical profiles of these gases.
Consider the most interesting components of the vector of the retrieved
parameters, namely the optical parameters of the atmospheric aerosols. The
examples of retrieving the vertical profiles of the aerosol scattering and absorp-
tion volume coefficients are presented in Figs. 5.7-5.9 and in Tables A.8-A.11
of Appendix A. Note that they are significantly lower than the a priori ones in

the results upon zeroth approximation selection should be stressed (Zuev and
