Dear All

I have a problem with the chemistry output.

I make a run using RegCM-4.4-rc10, with chemsimtype = 'CARB' , but after running the model, in the output files after the first time step, the concentrations start in decreasing to be very low over the domain, so where is the error?

the namelist and the output file are attached.

thank you in advance.

Best Regards
