Re: [arts-users] ARTS 2.5.0 - absorption
Dear Mattia,
It looks like you are removing line calculations from your lookup
calculations.
Could you try adding abs_xsec_per_speciesAddLines to your lookup
cross-section agenda? I think this will solve the problem.
We are currently in a transition in the 2.5-branch of moving away from
abs_xsec_agenda entirely. There are some lingering problems when using
lookup table calculations at this time. Mainly, since the line
calculations should happen in propmat_clearsky_agenda now, they are not
part of any of the default cross-section agendas as in the past. The
lookup generation interface is currently under active development, so this
interface might change in the near future.
With hope,
//Richard

Re: [arts-users] read in HITRAN par file
Dear Pengwang, You should be able to read a Hitran file in 2.4 that you could read in 2.3. Now, it sounds like you have downloaded a new version of the Hitran catalog. Arts 2.4 does not directly support Hitran2020, neither did 2.3 to be clear. For water, I still think this should still be Ok but I am not sure. If you want to give it a try, the 'modern' way of dealing with Hitran data in Arts is to download it with the additional tags in the Hitran download interface. On the tab currently called '4. Select or Create Output Format'*, you can create a new output format. To create a new format that works well with Arts, this format should contain at the top the ".par line" tag, as the second option it should contain the " qns' " tag, and as a last option it should have the " qns'' " tag. The field separator and line endings should be the default ([tab] ; (CR LF)). If you manage to download data like this from Hitran, you can give the hitran_type="Online" option in ReadHITRAN. This should give decent results. Again, remember that Arts 2.4 is from before Hitran2020 was released. It is possible this will not work in 2.4. What I describe above works for the development version of Arts (v.2.5). With hope, //Richard * From hitran.org, Data Access -> Line-By-Line -> select H2O and go forward -> go forward (or deselect some isotopologues first) -> go forward (or select some Kayser range first) -> You are now on the right tab to specify output format Den tors 3 feb. 2022 kl 16:06 skrev Pengwang Zhai : > 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”.

[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. Appreciate it very much, Yours, Pengwang ___ arts_users.mi mailing list arts_users.mi@lists.uni-hamburg.de https://mailman.rrz.uni-hamburg.de/mailman/listinfo/arts_users.mi
Re: [arts-users] cannot compile the latest version of ARTS
Hi Pengwang, Thanks for reporting this bug. I'll merge a PR with a fix soon. See https://github.com/atmtools/arts/pull/394 However, if you don't plan to use or modify the lookup tables outside of ARTS, I recommend that you save them as binary XML instead for best efficiency: WriteXML( "binary", abs_lookup, "lookup.xml" ) Cheers, Oliver > On 8 Feb 2022, at 20:02, Pengwang Zhai wrote: > > Hello, > > I had some issue with arts 2.4 in reading HITRAN par file.
