| |
===== 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:** NF_2006-2008_AER_AMIP_OBS | |
| |
**Model type:** Stand-alone cam (atmosphere) default with prescribed ocn/ice (ocean and sea-ice) | |
| |
**Type of run:** Branch | |
| |
**Simulation period:** 3 years | |
| |
**Spin-up period:** 0 years in the branch run itself, but continued from 1979-2005 | |
| |
**Ensemble runs:** No | |
| |
**Resolution:** f19_f19 = 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 RCP8.5 emissions (aerosols and precursors) for year 2006-2008 | |
| |
**Frequency for output:** Monthly | |
| |
**Active/changing forcing agents:** In principle, direct and indirect (1. & 2.) effects by anthropogenic SO4, POM and BC, but aerosols were run offline (not affecting the meteorology) | |
| |
| |
**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) | |
