[RegCNET] Problem in running RegCM3 with aerosol

[Nguyen Ngoc Bich Phuong]

Dear all,
I am trying to run RegCM3 model with aerosol for 3 months,
cases:
1. SO4
2. BC_HL
3. Original (no aerosol)

When I run the model with aerosol: I use 'AERTYP = AER01D0'; ifchem = 
'true'; ichem = 1; idirect = 1; chtrname= BC_HL or SO4;
in file "parame" : ntr = 1; nbin =1

When I run the model without aerosol: I use 'AERTYP = AER00D0'; ifchem = 
'false'; ichem = 0; idirect = 1
in file "parame" : ntr = 0; nbin =0

All output ATM.xxxxxx  in three cases  are the same, like I count 
average temperature of the last month and compare between them, minus 
each other and result = 0 but CHE.xxxxxx in two cases 1 and 2 are different

I have no idea about this problem, please tell me if you find my 
problem. I respect of it very much.

With Best Regards,
Phuong
