Dear all,
Hi all, please spent a little time reading my letter, and please give me suggestions, thank you very very much!
I want to use megan emission to do a 3-nested domain run with WRF/Chem 3.3.1, but facing error " bioemdt needs to match the model time_step."

My time_step is 150(s), and biemdt is 2.5(min), they are definately matched, but I still got the error when I run wrf.exe : bioemdt needs to match the model time_step.
I really don't know why...
Dear Sir or friends, please spent a little time reading my letter, and please give me suggestions, thank you very very much!
