Papers in preparation:

Simulation name(s): aerocomA2noresm_r128_X, where X = 2006 (AeroCom-A2.CTRL), 1850 (AeroCom-A2.PRE), ZERO (AeroCom-A2.ZERO), 2006preSO4, 2006preffBC, 2006preffOC and 2006prebbBCOC

Compset name used: NFAEROCOM1850 for X=1850, NFAEROCOM2006 for the other experiments

Model type: Stand-alone cam (atmosphere) default with prescribed ocn/ice (ocean and sea-ice)

Type of run: Initial

Simulation period: 5 years

Spin-up period: 2 years

Initialisation:

Resolution: f19_g16 = 1.8×2.5

Emission year(s): 2006 (AeroCom-A2.CTRL), 1850 (AeroCom-A2.PRE), 2006 but with aerosol extiction set to 0 (AeroCom-A2.ZERO). For X = 2006preY all emissions are for year 2006, except that 1850 emissions are used for: SO2 and SO4 in the Y = SO4 experiment, fossil fuel BC / OC in the Y = ffBC / ffOC experiment, and biomass BC and OC in the Y = bbBCOC experiment.

Emission inventories: IPCC AR5 for 1850, AeroCom Phase II for 2006, see references in Kirkevåg et al. (2013)

Greenhouse gases: Prescribed concentrations

Frequency for output: Monthly

Active/changing forcing agents: Direct and indirect (1. & 2.) effects by anthropogenic SO4, POM and BC (for X = 2006 - 1850), or by all aerosols (2006 - ZERO, only direct effect), or by anthropogenic SO4 (2006 - 2006preSO4), ff BC (2006 - 2006preffBC), ff OC (2006 - 2006preffOC), or anthropogenic bb BC & OC (2006 - 2006prebbBCOC)

Special considerations:

Tuning parameters which are changed relative to the host model CAM5:
