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= 1.9×2.5 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)
