Thank you, I've solved this problem, it is because of the wrong absorption
models I've choosed. thanks again.

Hello,
Your control file is not running because the `abs_species` workspace variable
is not set.
Could you please check if you attached the correct control file?
Best wishes,
Lukas

Dear,
I'm a new user of ARTS, recently I'm using the newest ARTS 2.3 and radiosonde
data to do a simulation for a groud-based microwave radiometer, the question
is, the simulated BT have a significant bias compared with observed one at
water vapor channel, and i don't know how to correct it, is there someone could
help me?
the following is my script. thanks.
