solar input help

[clchen@ouc_edu_cn]

Hi,
I want make a ccsm run test. But I don't konw how to put "Solar forcing" into the running. My "/atm/atm.stdin" file is showing like this:
&camexp
caseid = 'test'
ctitle = 'test test'
brnch_retain_casename = .true.
ncdata = 'b30.004.cam2.i.1000-01-01-00000.nc'
nrevsn = ' '
aeroptics = 'AerosolOptics_c040105.nc'
absems_data = 'abs_ems_factors_fastvx.c030508.nc'
nsrest = 1
dtime = 1200
start_ymd = 19900101
linebuf = .false.
nelapse = -9999
flxave = .true.
rest_pfile = 'rpointer.atm'
mss_irt = 0
bndtvo = 'A2.ozone.128x64_L18_1991-2100_c040528.nc'
bndtvaer = 'AerosolMass_V_64x128_clim_c031022.nc'
scenario_scon = 'RAMPED'
bndtvscon = 'scon_hs_1870-2100_c040211.nc'
scenario_ghg = 'RAMPED'
bndtvghg = 'ghg_ipcc_A2_1870-2100_c040521.nc'
bndtvg = 'noaamisc.r8.nc'
/

the ghg is RAMPED succefull, becuse I can see it in the atm.log* file when running, but I'm no sure whether solar forcing is added, the atm.log* file does not output any informations about it.
How can I confirm the solar forcing is successfully added to the model?
Thanks!
