Notes
The same species profiles are written as in the
.rtv output except that here the
profiles extend for full atmosphere used in internal forward model
(so included fixed as well as retrieved profile levels), and
no SD profiles or diagnostic information (such as information content)
are included.
The .orb files can be used for passing
the output of one retrieval as input to another,
input via the *ATM section
of the driver table.
