| |
| ===== Model-run description for a simulation with CAM4-Oslo (NorESM1-M) (UNDER CONSTRUCTION!) ===== | |
| |
| **Purpose of simulation:** Model validation for the Arctic under PD conditions | |
| |
| **Contact person:** Alf Kirkevåg (alf.kirkevag@met.no) | |
| |
| **Revision Number:** r164 | |
| |
| **Production computer used:** Cray XT6 in Bergen (hexagon) | |
| |
| **Production date:** October 2013 | |
| |
| **Storage locations:** NorStore (/norstore_osl/projects/NS2345K/noresm/cases/NF2006to2008r164/) | |
| | |
| MET Norway (/vol/fou/atmos/alfk/aerocomA2ny/aerocom.CAM4-Oslo.AEROCOM_A2.CTRL/) | |
| |
| **Storage space:** 9 (?) Gb at NorStore, 25 (?) Gb at MET Norway (local external disk) | |
| |
| **Projects:** EarthClim/ACCESS | |
| |
| **Publications:** | |
| |
| **Papers in preparation:** Glantz et al. (submitted) | |
| |
| **Simulation name(s):** NF2006to2008r164 | |
| | |
| **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 = 1.8x2.5 | |
| |
| **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) | |
