Hello, I'm wondering if attenuation due to gases when using iyRadarSingleScat is only considered where scattering particles exist. I'm trying to simulate backscatter for a 94 GHz 'radar' for liquid clouds containing liquid precipitation only, and I see that gas absorption is non-zero only within the cloud. That is, there is zero attenuation in clear sky regions even though water vapor values are quite high. I would think attenuation due to water vapor would exist above cloud (for nadir looking sensor) as well as below cloud (for zenith pointing sensor). I've tried using 'LookUpTable' as well as 'OnTheFly' calculations for 'propmat_clearsky_agenda', but neither seem to output gas absorption at 94 GHz in clear sky regions.
