[RegCNET] 6 Aerosols AOD distribution

[Yan Libin]

 Hi, Dear regcmers,

 I made an regcm run including 6 aerosols as follows,

  $
   $chemparam
  idirect   =    2,
  chtrname  =
 'SO2','SO4','BC_HB','BC_HL','OC_HB','OC_HL',
  chtrsol   =  0.20, 0.80, 0.05, 0.80, 0.05, 0.80,
  chtrdpv   =
 0.00300,0.00200,0.00025,0.00025,0.00025,0.00025,0.00800,0.00200,0.00025,0.00250,0.00025,0.00250,
  dustbsiz  =  0.01, 1.00,
  $

 And attached is figure output of the 6 aerosols total AOD by using sum function in GrADS software.
 'define aod=sum(aext8,z=1,z=18)'
 'd ave(aod,t=1,31)'
 But the values are between 0.- 0.1 which are much less than normal AOD values(0.-1.0, seen as attached MODIS observation output)
 Are the simulated values right?
 I can't find out which step I was wrong.
 The values of original total vertical aext8 are actually between 0. - 0.1
 Has anyone done similar experiments?
 Please give me some advices about this.
 Thank you very much in advance.

 Regards,
 Libin Yan
