[arts-users] Issues using "scat_data" in ARTS dev version

Dear ARTS Community, I am using the dev version of ARTS to use some of the newer workspace methods and was experiencing issues with "scat_data". After loading 'scat_data,' the values say: "SingleScatteringData: Output operator not implemented." As this was not an issue with the stable ARTS 2.4

Hi Everyone, I had some questions about the calculated brightness temperature in ARTS. When I calculate the brightness temperature for an atmospheric scenario in "horizon looking mode" and in clearsky. I get a brightness temperature at 183.31 GHz (Water vapor absorption line), which is about 3

[arts-users] ARTS Scattering Jacobians

Hi Everyone, I had a couple of questions about jacobian calculations in ARTS. The ARTS user guide in chapter 16 mentions that none of the scattering methods can provide jacobians, and currently only works in clear sky cases. But, the ARTS built-in documentation shows the methods
