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.

Bye,

Patrick

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
