Hi everybody,
 
The value of aext8 puzzled me.
 
That's the situation, I added dust plus all aerosol (SO,OC and BC) in my experiment.
 
I set aertyp=AER11D1
            ntr=10
           nbin=4
inpchtrname='DUST','DUST','DUST','DUST', 'SO2','SO4','BC_HB','BC_HL','OC_HB','OC_HL' .
 
I want to know if the value of aext8  is total value of all aerosol (include dust), or the model  only caculate only one kind of aerosol (maybe the first one dust) in the case of too many aerosols.
 
Thanks
