Hi Patrick,
Thank you for your help. It is indeed very difficult to achieve inversion of
temperature and humidity profiles under cloud conditions. I have another
question, is it in the planetary toolbox that the best way to use it is iyFOS
or iyDOTIT? IyMC seems too slow.
At
Hi,
Very hard to answer without more specific information what you want to do.
If you want to do OEM-type inversion involving scattering, then iyHybrid
is the only option inside ARTS. It is reasonable fast, if used with e.g.
DISORT.
DISORT is the fastest scattering solver inside ARTS, but
Hi Patrick,
Thanks again for your help! Is the iymc method generally slower than the iydoit
method? If the radiative transfer rate calculated by the scattering method is
very slow, does it mean that it is difficult to invert the atmospheric
temperature and humidity profile from the scattering
Hi,
In general, it works perfectly fine to use PlanckBT from start. But
could depend on the calibration of the instrument you simulate.
There is one exception, and that's iyMC. It does not accept PlanckBT,
just RJBT.
Bye,
Patrick

Hi Patrick,Thank you for your help! Based on your suggestion, I will no longer
use iyfos and instead use iyMC to handle scattering situations. But I have
another question that confuses me. I often see routines that use StringSet
(iy_unit, "1") for unit conversion before calculating scattering,
Hi,
FOS is "dead" and no plans to get it back to live.
A main reason for starting FOS was to have scattering calculations,
providing the Jacobian. This was newer completed. Instead, also iyHybrid
was started and that method provides a Jacobian (not the totally full
one, but seems to be good
Dear ARTS community,
I am dealing with scattering situations and have used the iyFOS method in
Arts-2.2 version, but there is no FOS method in Arts-2.4. May I ask if the
method name has changed? I know and have consulted relevant literature on MC
and DOIT methods, but is there any reference
