====== N20TRAERCNOCBPRP_EXPECT01 ====== ===== 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:** 249, 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_EXPECT01 ) **Storage space:** ?? **Projects:** EXPECT **Publications:** **Papers in preparation:** **Simulation name(s):** N20TRAERCNOCBPRP_EXPECT01 **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: ** Note that the number of cores used for historical runs was changed in revision 249. Earlier historical runs were too slow. A "bug" in was fixed. Do svn diff -r 249:246 to see the changes in noresm/scripts/ccsm_utils/Machines/config_pes.xml. Earlier version will not give bit identical results to this run even using same compset. **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)
