Hi,
I used earlier version of ARTS to calculate the total absorption coefficients
with:
abs_coefCalc
and found it is very useful. Now with the new version, this does not work any
more. After reading the change log I found that it is replaced with
abs_coefCalcFromXsec
However, after numerous
alc method are obsolete and not supported anymore.

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
Hi,
I am trying to use ARTS to calculate the absorption coefficients
(propmat_clearsky_field) for wavelengths between 860 nm and 1060 nm. If I use
abs_speciesSet( species=[ "H2O-PWR98”])
I get numbers ridiculously large (~2500 1/m). If I just use
abs_speciesSet( species=[ "H2O”]),
I get rea
Thanks, Jana. This is really helpful.
In my point of view, it should be very easy/better to program the range within
ARTS. I agree that users need to be keen on what they do. However, they may
not know everything at times. It would be much better to implement these small
things and avoid po
rptions too. Put a frequency,
temperature, pressure sanity check for all models should be the first priority
to do for ARTS.

Dear ARTS fans,
I intent to use ARTS to obtain gas absorption coefficients for major gases,
base on HITRAN 2012 database. In the main page of ARTS, one of the current
limitation is:

• not suitable for shortwave calculations (near IR-UV)
• no absorpt
Dear Stefan and Claudia,
I downloaded reptran from libradtran.org following the instruction in the paper:

Dear ARTS developers:
ARTS is an invaluable tool for the RT community and thanks very much for your
great contribution.
I have recently run into a problem with HITRAN 2016, the newest version of
HITRAN. I have downloaded the O2 par file from the HITRAN website. It is named
as: 5a4fe828.par. I

arts reports:
"Run-time error in method: ReadHITRAN

Is there any way we can read in HITRAN par file and create a lookup table? Do
you suggest me going back to arts 2.3?
Thanks for your advice,

Hello,
I had some issue with arts 2.4 in reading HITRAN par file. I was advised to use
the latest version of arts. I did the following:
git clone https://github.com/atmtools/arts.git
cd arts
mkdir build
cd build
cmake -DENABLE_NETCDF=1 ..
make
The compilation stoped at 25%, with the following e
Hello, ARTS community,
I downloaded and compiled the latest version of arts. Now I tested the the
creation of abs_lookup with the example control file located in:
arts/controlfiles/artscomponents/absorption/TestAbs.arts
I only modified two occurrences of:
abs_speciesSet( species=[ "H2O-PWR98"
esAddConts.html).

I did see the same warning that you saw regarding abs_xsec_per_speciesAddLines.
