Dear Simon,
thanks for the summary!
I think I understand more or less how this works now. A bit unfortunate
that so much information has to be moved around at the controlfile
level. (The copying of grids from one variable to the other, the copying
of the scattering data themselves.) Is the idea that you would then in
practise store and load directly the ScatteringHabits, in order to make
this easier?
On where the Rayleigh scattering fits in: Patrick suggested when we
talked yesterday that perhaps a more logical way to think about this is
to distinguish between *gases* and *particles*, rather than between
*absorption* and *scattering*. (Including Rayleigh scattering with the
PND system really does not work, as it turns out, as it depends on
pressure.)
Perhaps we should move towards a *gas* / *particle* division in ARTS.
That would mean including the Liebe rain absorption in the particle
part. It would also affect your nomenclature, since one should then
preferably talk about *ParticleSpecies* rather than *ScatteringSpecies*.
(And *gas_species* instead of *absorption_species*.)
All the best,
Stefan

Dear Stefan,
I attach the description of the new scattering system that you
requested.
I tried to keep it general to avoid getting lost in technicalities. If
you have
more specific questions please let me know.
Kind regards,
Simon

Subject: Simon plans for scattering properties
Dear all,
one thing I took home from the developer meeting on Friday is that I
would like to better understand Simon’s plans for the scattering
properties. We need this to make a good decision on how to proceed
with
the Rayleigh scattering (incorporate it into the existing scattering
data framework, or make a special case for this analytical scattering
matrix). Simon, can you please summarize your concept briefly?
All the best,
Stefan
