Hello,

I appreciate if anyone would like to help me out of this question,

In my research we want to add a passive tracer in model. This part has been mentioned in forum,which is coded in dyn_em/solver_em.

Then we want to see the effect of this passive tracer onnee the microphysical process using SBM. So

I need to add this tracer to a microphysical variable, say QNIN.

Following the wrf output variable process, I declare a new variable in SBM

tr_two

and transmit to module_microphysics_driver TR_TWO. TR_TWO=tr_two

and then to solver_em, where the tracer2 is calculated.

When I linked them together, I found that TR_TWO is zero, which is TR_TWO=tracer(ims,kms,jms,P_N_TWO), while tracer(ims,kms,jms,P_N_TWO) is not zero in solver_em.

I am not understanding where I made mistakes. Why they can not transmit as the variable output from microphysal schemes.

In case of my expression not clear, please find my attached file related. Here are the variables name tr_two in module_mp_full, TR_TWO in module_microphysics_driver, and tracer( ims,kms,jms,P_N_TWO) in solver.

THANK YOU VERY MUCH FOR YOUR HELP.
