(All mentioned files are in /glade/p/cesmdata/cseg/inputdata/atm/cam/chem/trop_mozart_aero/aero/; I'll be excluding that for clarity.)

When requesting an ssp370 compset, the default aerosol file is aerodep_clm_SSP370_b.e21.BWSSP370cmip6.f09_g17.CMIP6-SSP3-7.0-WACCM.001_2014-2101_monthly_0.9x1.25_c190402.nc, which starts in 2014. Instead, per conversation just now with @ekluzek, it should probably be aerodep_clm_SSP370_b.e21.BWSSP370cmip6.f09_g17.CMIP6-SSP3-7.0-WACCM.001_1849-2101_monthly_0.9x1.25_c201103.nc.

There's also aerodep_clm_SSP370_b.e21.BWSSP370cmip6.f09_g17.CMIP6-SSP3-7.0-WACCM.001_1849-2101_monthly_0.9x1.25_c201101.nc, which differs from the _c201103.nc version in number of timesteps (3059 vs. 3036, respectively). Since the _c201101.nc number of timesteps isn't evenly divisible by 12, it's probably not the right one to use.

The files that should be used are the ones that we point to in the PLUMBER2 user-mods for CTSM as seen here:
