At one point, I was running a version of the single scattering radar code internally that used mc_antenna to sample a Gaussian beam. This could be applied similarly to the independent pixel approximation for the passive sensors, but the way I did it seemed very redundant. I never folded your

Dear Ian, I also agree. In fact, I hope that we could use MC much more widely in some future version of ARTS, perhaps all the way down to MC sampling individual spectral lines. /Stefan On 7 Dec 2023, at 8:27, Patrick Eriksson wrote: > Ian, > > Thanks for the input. Great that you have

Ian, Thanks for the input. Great that you have stress-tested MC. Too bad that it revealed a limitation. Good suggestion about iyMC. Today it would not be possible to do the random sampling from yCalc, it would require information on the sensor not at hand inside yCalc today. But we are

Hi Stefan, I have been contemplating changes to the MC codes. One thing we have found is that MCGeneral breaks down when Q starts to get large. We see unrealistic results at 684 GHz when using horizontally aligned particles with high aspect ratio. Yuli Liu, who is working with us now, did
