CCSM4 volcaero/aerodep


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 ( 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 (, 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,
