====== n20traercnocbprp_ce02 (n20traercnocbprp_ce01) ====== ===== Model-run description for historical run used in EXPECT ===== **Purpose of simulation:** Historical run for expect model version **Contact person:** Jerry Tjiputra **Data owner: ** Jerry Tjiputra **Revision Number:** 246, https://svn.met.no/NorESM/noresm/branches/projectEXPECT_cmip5-r143-1 **Production computer used:** Cray XT3 in Bergen (hexagon) **Production date:** Spring 2014 **Ensemble runs:** No **Storage locations:** NorStore (/projects/NS2345K/noresm/cases/n20traercnocbprp_ce01), where X = ensemble member, X=1,2,3 for this particular set-up **Storage space:** ?? **Projects:** EXPECT **Publications:** **Papers in preparation:** **Simulation name(s):** n20traercnocbprp_ce02 (n20traercnocbprp_ce01) **Compset name used:** N20TRAERCNOCBPRP **Model type:** Fully coupled **Type of run:** Hybrid **Simulation period:** 1850-2005 **Initialisation ** Started as hybrid run from N1850BPRPCNOC_f19_g16_spin_02 with restart files from "0501-01-01". This date maps to 1850-01-01 in this run. **Resolution:** f19_g16= 1.9x2.5 degree atmosphere/land. Dipolar ocean/ice grid, ~ 1 degree **Emission year(s):** 1850-2005 **Greenhouse gases:** Interactive CO2 **Emission inventories** N/A **Frequency for output:** Monthly and selected daily **Active/changing forcing agents:** Greenhouse gases: Direct and indirect (1. & 2.) effects of SO4, POM and BC. ** Special considerations: ** ** This model configuration has been used in two simulations: n20traercnocbprp_ce01 and n20traercnocbprp_ce02: The "01" simulations must have been started with some slightly changed source code, since we were never able to reproduce the results. The n20traercnocbprp_ce02 simulation is bit reproducable with the instructions given in this model description file. ** **Tuning parameters which are changed relative to the host model NorESM-CMIP5-branch:** * rhminl: 0.9005 lower RH threshold for formation of low stratiform clouds (0.91 in CAM4)
