Re: [arts-users] Compatibility with HITRAN2016
Thanks, Oliver. I tried your recipe and it works fine to me. Another small thing (or bug) is that arts LUT function sometimes generates small negative values for absorption coefficient, when the spectral regions is slightly outside an absorption band. If the developers are interested in fixing this problem, I would be happy to provide more info that I have.

[arts-users] Compatibility with HITRAN2016
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 used the example script to calculate the absorption Look-Up-Table. One function is: abs_linesReadFromHitran( abs_lines, “~/Oxygen_HITRAN2016/5a4fe828.par", 1.3e+14, 1.0e+15 ) Then I got the following error message: Run-time error in method: abs_linesReadFromHitran ‘~/Oxygen_HITRAN2016/5a4fe828.par' does not appear to be a HITRAN 2012 catalogue. The catalog filename must start with HITRAN2012. If you intend to use a HITRAN 2008 catalog run 'cmake -DWITH_HITRAN2008=1 ..' and recompile arts Stopping ARTS execution. Any suggestion to make this work? Have you attempted to confirm the compatibility with HITRAN 2016? My arts version is: arts-2.3.657. Thanks very much and have a great 2018!

[arts-users] Cannot create abs_lookup with arts 2.5
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", "O2-PWR93", "N2-SelfContStandardType" ] ) to: abs_speciesSet( species=[ "H2O" ] ) and run arts TestAbs.arts The resultant abs_lookup are all ZEROs. Any help? More background information: I used arts 2.3 to create abs_lookup for H2O, CO2, etc. in the visible by reading from HITRAN 2012. The baseline example was TestAbs.arts provided by the arts installation. Now I need to revisit the calculation based on HITRAN 2020, and the lookup table calculation seems not working with arts 2.5. I greatly appreciate it if you could provide a working example on how to create a abs_lookup with arts 2.5.

Re: [arts-users] Cannot create abs_lookup with arts 2.5
Hello, Mattia,
Thanks for the update. I have to admit that I did not use the line.xml file. I
used the H2O file downloaded from HITRAN 2020. Originally I said “it seems
working”, today I still cannot definitely confirm whether it works from my
side, as ARTS 2.5 did not finish the calculation after several days. Maybe I am
trying to calculate too many frequency lines, though I believe ARTS 2.3 only
took several hours to build the same lookup table.
I did see the same warning that you saw regarding abs_xsec_per_speciesAddLines.
Yours,
Pengwang

[arts-users] read in HITRAN par file
Hello, ARTS Community, I used arts 2.3 to generate gas absorption coefficient lookup table for o2, co2, etc. One key function was: "abs_linesReadFromHitran”. Now I need to revisit the calculation with HITRAN2020. I thought I would use arts 2.4, a newer version. After successfully compiling arts2.4, and run the same .arts file I used before (a modification of TestAbs.arts), arts tells me that “abs_linesReadFromHitran” is not available any more. I went over the documentation, and found “READHITRAN”. I tried the following: ReadHITRAN( abs_lines, “./h2o_61fbd3ce.par", 1.3e+14, 1.0e+15 ) arts reports: "Run-time error in method: ReadHITRAN Error parsing quantum number Sym”. 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?

[arts-users] cannot compile the latest version of ARTS
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 error message: /arts/src/nc_io.h:37:10: fatal error: 'abs_species_tags.h' file not found #include "abs_species_tags.h" ^~~~ 1 error generated. make[2]: *** [src/CMakeFiles/artscore.dir/auto_md.cc.o] Error 1 make[1]: *** [src/CMakeFiles/artscore.dir/all] Error 2 make: *** [all] Error 2 Any suggestion here on how to fix this? Note that my purpose is to create an absorption lookup table from HITRAN 2020. I need the NetCDF support to make the resultant absorption lookup table manageable.

Re: [arts-users] Cannot create abs_lookup with arts 2.5
Thanks, Oliver and Mattia, for you help.
After studying Mattia and Richard's posts, I figured out the following:
Comment out line 15 of TestAbs.arts:
#Copy(abs_xsec_agenda, abs_xsec_agenda__noCIA)
And insert the following to line 16:
AgendaSet( abs_xsec_agenda ){
abs_xsec_per_speciesInit
abs_xsec_per_speciesAddConts
lbl_checkedCalc
abs_xsec_per_speciesAddLines
}
Now it seems working, though I have not yet got the chance to check the outputs
as it is still running.
Yours

Re: [arts-users] Cannot create abs_lookup with arts 2.5
Thanks, Mattia. Would you advise how TestAbs.arts can be revised to include
line-by-line calculation?
Note that the behavior of TestAbs.arts is different in arts2.3, which does
calculate line-by-line absorption coefficients.
I do not want continua, as I am mainly interested in the visible spectra, which
is out of most of those continuum models. Based on my experience with previous
arts version, arts does not check the spectrum limits for the continuum models.
I am not sure whether arts 2.5 has been improved on this.
