Dear Pengwang,
please take a look at the workspace variable propmat_clearsky_field (and
the workspace method propmat_clearsky_fieldCalc, that calculates this
variables). Could they probably provide the output you need?
abs_coef and its *Calc method are obsolete and not supported anymore.
Best wi
Thanks, Jana. Too bad that the only arts feature that I am using is now
obsolete.
Now given propmat_clearsky_field, can I somehow obtain abs_coeff from it?
I used the following commands to create abs_coeff_user, which is the absorption
coefficients per specie,
Tensor3Create(abs_coeff_user)
Re
Hi,
what do you intend to do with abs_coeff_user?
Do you really process this further within ARTS itself? only then it makes
sense to process propmat_clearsky_field into a Tensor3*, i think.
Else, I strongly recommend to do any re-shaping / reduction outside of
ARTS; other programming languages are
Thanks, Jana.

This is exactly what I wanted to do within arts to get “abs_coef”. If it is
not possible with arts, I will use matlab to do this.

Dear Pengwang Zhai,
I think we still have what you are looking for in ARTS.
The variable you are actually interested in is not abs_coef, but
abs_coef_per_species.
The way to create this is to first run abs_xsec_agenda and
then abs_coefCalcFromXsec.
I think your code should only change from:
ab
Thanks, Richard. I tried your suggestion. Unfortunately, it does not work.

Dear Pengwang,
Yeah, you have to copy abs_species to abs_species active. I forgot about
that. The Copy( out, in ) function does that so add
Copy( abs_species active, abs_species)
before you call the xsec agenda.
To explain the reasoning for the active tag: Not all species can be
handled by t
Erratum,
Sorry, this was wrong of me. You have to create an ArrayOfIndex of the
active species. So you need to load an ArrayOfIndex the length of
abs_species and fill it with 0,1,2,3,4,5,...n-1, where n is the number of
species you are using.
Sorry about the spam,

Thanks very much. Now it still does not run. See:

Thanks very much, Richard. I am not sure how to do this then. I would
appreciate it very much if you could provide a template.
I need abs_coef, which is the total absorption coefficients for all gas
species. Then I mix the gas absorption with aerosol and cloud scattering
properties and use t

I tried different software package for this purpose, and found ARTS is one

Thanks, Jana. Your email explains much of my confusions now.
I will use propmat_clearsky_field and calculate abs_coef from it using other
scrips, matlab, for example. The only problem is the burden of figuring out a
7 dimension tensor text file layout, but I will get there eventually.
Thanks
