Hi,
The only way to get ARTS to do QV and QH automatically, is to use a
"system" denoted as metmm. You find it in folder
arts/controlfiles/instruments/metmm
It is not totally straightforward to use and the documentation is not
extensive. As far as I know, the documentation is basically the file
TestMetMM.arts.
The sensor definitions are found in sub-folder sensor_descriptions.
Inside these QV and QH are denoted AMSU-V and AMSU-H. This assumes that
QH and Qv work in the same way for all cross-track microwave radiometer.
I assume this is true, but I am not 100% sure.
Bye,
Patrick

Dear ARTS community,
ARTS provides calculation methods for vertical polarization and
horizontal polarization. However, many sensors are now set up with QH
and QV polarization. I simulated the brightness temperature of a
satellite borne microwave radiometer channel at 23.8GHz (QH
polarization) over the ocean using a one-dimensional atmosphere, and the
first Stokes vector I obtained was close to the observed QH polarization
brightness temperature. However, the simulated brightness temperature of
H polarization （instrument_pol, [6] ) was significantly different from
the observed QH brightness temperature, May I ask if it is possible to
simulate the QH polarization of spaceborne radiometers through the H
polarization of ARTS? Is it still possible that I input other variables
incorrectly?
Looking forward to your reply！Thank you!
Best wishes,
Jiaan He
