We have a bunch of single forcing runs using the cesm1_0_beta20 tag. (compset B_1850_CAM5_CN) We'd like to move some of these runs over to yellowstone, but our only compatible model version is CESM1.0.5. When looking at the answer-changing features on the CESM1.0 line, I saw that with CESM1.0.2, there was a change to the GHG dataset. This would make the CESM1.0.5 incompatible for us since our runs are looking at attribution due to things like GHGs. However, I saw that cesm1_0_beta20 was created on 5/16/2011 and cesm1_0_2 was created in Dec. 2010. Does this mean that the newer GHG file used in CESM1.0.5 is the same as that used in cesm1_0_beta20? Where could I look to verify this?Thanks!Susan
change GHG forcing for 1850 control in CESM1.0.5

You can look which files the model uses in your namelist or in the directory models/atm/cam/bld/namelist_files/use_cases:Assuming you are doing at transient run:cesm1_0_5 and cesm1_0_beta20 both use:atm/cam/ggas/ghg_hist_1765-2005_c091218.ncThis is the greenhosue value recommended for CMIP5 runs.
