Hi @cxyiyh

While I'm not sure what happened with your specific case, most often what happens with convert emiss is that the program runs out of memory. Try supplying the job with more memory when you run. If that does not solve the problem, you can try an older version of the covert emiss tool. Or you can try compiling the program with debug options. Otherwise what is often suggested is to use the HERMES program (https://gmd.copernicus.org/articles/12/1885/2019/) to generate the emissions for your domain. I apologize we cannot be of more help.

Hi, @Jordan
Thanks,If I use wrf-chem3.6.1,it will be successful.Obviously, now I get my emission DATA by wrf-chem3.6.1, then use WRF4.2 to run.Thank you again for your reply.
