Production date: August 2010

Storage locations: NorStore (/norstore_osl/projects/NS2345K/noresm/cases/aerocomA2noresm_r128/)

MET Norway (/vol/fou/atmos/alfk/aerocomA2ny/aerocom.CAM4-Oslo.AEROCOM_A2.CTRL/)

Storage space: 289 Gb at NorStore, 6 Gb at MET Norway (/vol/fou)

Publications: Kirkevåg et al. (2013), Myhre et al. (2013), Samset et al. (2013), Jiao et al. (2014), Tsigaridis et al. (2014)

Papers in preparation: Samset et al. (submitted), Huttunen et al. (in prep.), Kipling et al. (in prep.), Koffi et al. (in prep).

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

Ensemble runs: No

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)

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)

Tuning parameters which are changed relative to the host model CAM4:

rhminl: 0.90 lower RH threshold for formation of low stratiform clouds (0.91 in CAM4)

critrp: 5.0 mm/day maximum prcipitation rate for suppression of autoconversion of cloud water (0.5 mm/day in CAM4)

r3lc: 14 um critical mean droplet volume radius for onset of autoconversion (10 um in CAM4)
