The internal profile contains profiles of temperature, pressure
and VMRs etc on the set of levels used for the internal forward
model. This is a combination of the user-supplied files in the
in the *ATM section interpolated to the first
height or pressure
grid (removing any VMR profiles for species not selected in the
*GAS section), plus any additional
levels that may be introduced by the
The profile is output in the same format as
.atm input files.
For 1D calculations a single file is written, but for 2D calculations
(GRA Flag) separate files are
written for every specified horizontal angle.
