Difference between versions:
1- HadGEM2-ES.A2.CTRL uses CMIP5 emissions (year 2000), nudged meteorology for 2006, all aerosol radiative effects included; 2- HadGEM2-ES.A2.HCA-0 uses Hindcast emissions (year 2006), nudged meteorology for 2006, all aerosol radiative effects included; 3- HadGEM2-ES.A2.CTRL-DIRECT uses CMIP5 emissions (year 2000), nudged meteorology for 2006, no radiative effects included;
So differences between 1 and 2 are the emissions, between 1 and 3 the aerosol radiative effects (which feedback on the aerosols in spite of the nudging, since the nudging does not drive the model, it's more a suggestion!).

Problem in CMIP5 output from CCCma (not AeroCom): We recently discovered a problem that affects diagnosed 3D tracer results in runs with CCCma models for AR5/CMIP5. A list of the affected variables is below. This concerns all runs that we did with any version of the CCCma model (CanESM2, CanAM4).The problem is limited to 3D results. There is *no* problem with the surface concentrations or burdens that were also provided to AR5/CMIP5. We just decided to remove the affected data sets from the Earth System Grid. There are currently no plans to replace these files, but this is certainly an option if projects rely on these results. List of affected variables: concoa / concbc / concso4 / conso2 / concdmc / concss / concdust

CAM4-Oslo-Vcmip5.A2 is the model version we would like the inter-comparison groups to use (for the time being, see below). It uses 2006 emissions of aerosols and precursors, but the meteorology is “climatological” (9999).
CAM4-Oslo-Vcmip5online.A2 is the same version as CAM4-Oslo-Vcmip5.A2, except that it has been run in online modus (thus giving different meteorology in CTRL and PRE), not offline as was required for the standard forcing experiments.
CAM4-Oslo-Vcmip5emi2000.A2 is the same version as CAM4-Oslo-Vcmip5.A2, except that it has been run with 2000 (instead of 2006) emissions, and only we only have data from 1 year (instead of 5 years). These data may be important for the direct radiative forcing study, since many/most other models seem to have been run with 2000 emissions but 2006 meteorology.
CAM4-Oslo.A2 is an old version and should not be used.
