CCSM4 volcaero/aerodep

Hello,

I'm trying to replicate, with changes, 20th century runs from CCSM4 using CESM1.0.6, and got stuck in the aerosol configuration. The original case (b40.20th.track1.1deg.005) namelist for CAM refers to a volcanic aerosol concentration file (CCSM4_volcanic_1850-2008_prototype1.nc) that is not present in the B_1850-2000_CN compset default namelist. On the other hand, the latter refers to a aerosol deposition file (aerosoldep_monthly_1849-2006_1.9x2.5_c090803.nc), which does not appear to contain anything specifically regarding volcanic aerosols.

So the question is, are those two related in some way, or was there a change in the aerosol representation between the CMIP runs and CESM1.0.6?

Thanks in advance,

Gabriel
