How to find number of Zun half layer for max_ts_level in WRF

Khin Myat

Hi all members,
While i was running simulation, i got the error that your max_ts_level must be number of zun half layer. Please, could you explain me about zun half layer and how do i find the number of zun half layer?
Thank you in advance for your time.
Any help is appreciated.

Hi Ming Chen,
Thank you very much for your reply.
I am sorry I did not save the rsl files but I took the screenshot of error message.
I attached the screenshot here.
At that time, I also had other errors because I did not set the mp_physics options for domain 5.

It seems that something wrong in your namelist. Please upload this file for me to take a look.

Dear Ming Chen,
Thank you very much. I uploaded my namelist here. When I reduce the max_ts level and I set the pyhsics option, then, the simulation ran successfully.

Thanks for letting me know. Note that max_ts_level should never be larger than the humber of WRF (half) vertical levels.
