Dear Wang,
yes, the differences between absorption models can be large at
individual frequencies, so the value is not impossible. Maybe Alex, here
on Cc, who is working at these frequencies and in this geometry could
also comment?
Best wishes,
Stefan

Dear Everyone,
I had some questions:
1. When I using line-by-line and MPM93（or PWR98） to calculate the
brightness temperatures, the difference between the results can be
more than 20 K at about 50 and 70 GHz in the nadir observation
(especially when the reflectivity is large). Is this expected ? In
other frequencies, such as 118 GHz, the difference is small.
2. when I using iy_surface_agenda in 2.4.0 (but it can be worked in
arts 2.3), error will occur:
Run-time error in method: AgendaSet
The agenda iy_surface_agenda must generate the output WSV
dsurface_rmatrix_dx,but it does not.
How can I solve it?
3. I extracted the scat data from the Single Scattering Databases. In
the test controlfiles, the data is read as:
ScatElementsPndAndScatAdd(
scat_data_files=["testdata/scatData/azi-random_f229-231T214-225r100NP-1ar1_5ice.xml"],
pnd_field_files=[""]
)
However, the data from the Single Scattering Databases can't be read
by this method since the format is different. Should I use
ScatSpeciesScatAndMetaRead instead?
Thank you very much. It is better if a demo contralfile could be
provided.
Regards,
Wenyu Wang
