Re: Bug in mozbc Execution

[Mary Barth]

Hello Da,

First, I would like to remind you that there is a Google email group for wrf-chem-mozbc questions. I have cc'd that group. It is very important to send your questions to this email group so that more experts can help answer it. 

Second, I am not aware of mozbc not being able to process data with longitude > 300 deg. If others are, then I hope to hear from them. 

In the meantime, it would be good to share the mozbc namelist with the group to confirm that you have set up the tool correctly. 

Thanks!

Mary

Dear Professor,

I encountered an issue while running mozbc to provide initial and boundary conditions for WRF-Chem. It appears that WACCM data can only be processed within the longitude range of 0 to 300 degrees. When the longitude exceeds 300 degrees, the program crashes with the following error message:

forrtl: severe (174): SIGSEGV, segmentation fault occurred

Could you please confirm whether this is a known bug in mozbc, or if I might have made a mistake in my setup? Any guidance on how to resolve this issue would be greatly appreciated.

Thank you for your assistance.

Best,
