Caroline,
Yes, the best would be if you could switch to the latest ARTS version. I
assume someone else can sort out your compiler problem.
Realised that I had the source code for ARTS 2.2 (but no running
version) and had a quick look. Things have changed more around Tmatrix
than I remembered. If you still want to generate scattering data for
arts 2.2, look at tmatrix/TestTMatrixSSD.arts
If I get it right, you have to apply Extract on scat_data_array. That
should give you data in the format of SingleScatteringData.
But maybe better to focus on the switch to latest ARTS ...
Bye,
Patrick

Thanks, Patrick for your reply.
I am using ARTS 2.2 as I am having problems getting the latest version
to run. This is not ideal, I'd rather run the most recent version, but
I am finding an error message "[module] requires the language dialect
"cxx17" , but cmake does not know the compile flags to use to enable
it.". I've updated all my compilers, but does not seem to fix this
issue. If anyone has any experience with this then do let me know.
Anyway, version 2.2 runs for clear-sky, so until I get the later version
going this is fine. I have compiled with fortran options to enable the
Tmatrix code, and I can use it to produce single scattering xml files.
These however, do not appear to be the format needed by the test file
TestDOIT, and I am getting xml syntax errors reported.
If there are any other sources of information out there with a few more
detailed examples on how to use this for clouds, I would really
interested to see them.
Thanks
Caroline

Caroline,
If you are using ARTS v2.2, the simplest way to obtain scattering data
in the correct format should be to use the Tmatrix code coming with
ARTS. This could need that you set some compilation flag.
Long time since I used v2.2. The method I talk about is now called
scat_data_singleTmatrix. I think it had the same name in v2.2, but I am
not sure.

Hi,
I am currently using ARTS2.2 to do simulations of cloud in the
microwave. I have a question that I hope someone can help with.
I have run though the clear sky example cases, and now I am trying to do
a 1D simulation of cloud. I've looked at the test DOIT example, and can
run that example, but now I want to be able to run one for my own
frequency range. As I understand it, I need to produce a Single
Scattering xml file for the appropriate frequency and
particle\temperature ranges. In the Test Doit example it uses the file
'p30f229-231T214-225r100NP-1ar1_5ice'. How do I produce a file like
this? I have run the python code demo_ssp4arts to produce SSP xml
files, but these are not an equivalent format to that needed in TestDOIT
and I get an xml parse error. I can't find any information about this
in the code\documentation.
Thanks
Caroline
