[RegCNET] DCCB chemistry option - sulfates?

[Peter Huszar]

Dear RegCM  users,

i have a question regarding the DCCB chemistry option in the 4.6.0 version:
The user guide days (Page 35):
"DCCB : Activate CBMZ +DUST +CARB + sulfate-nitrate-ammonium aerosol
calculated with the
ISORROPIA gas-aerosol thermodynamical scheme: 50 tracers are considered
here."
When I look at the code in mod_che_common, I find:

ntr = 50
which is ok, but when looking at the species list, I cannot find sulfates
 (like ANO3 and ANH4 that stands for nitrates and ammonium).


chtrname(1:ntr)(1:6) = (/'NO    ','NO2   ','N2O5  ','HNO2  ',&
                              'HNO3  ','HNO4  ','O3    ','H2O2  ',&
                              'CO    ','SO2   ','DMS   ','H2SO4 ',&
                              'CH4   ','C2H6  ','PAR   ','CH3OH ',&
                              'HCHO  ','ALD2  ','AONE  ','ETH   ',&
                              'OLET  ','OLEI  ','TOL   ','XYL   ',&
                              'ISOP  ','ONIT  ','PAN   ','HCOOH ',&
                              'RCOOH ','CH3OOH','ETHOOH','ROOH  ',&
                              'MGLY  ','ISOPRD','ISOPN ','OPEN  ',&
                              'CRES  ','NH3   ','DUST01','DUST02',&
                              'DUST03','DUST04','BC_HL ','BC_HB ',&
                              'OC_HL ','OC_HB ','SSLT01','SSLT02',&
                              'ANO3  ','ANH4  ' /)

Can somebody explain me, why it is so?

Thanks a lot in advance
With regards,
Peter
