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= 1.9×2.5 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: 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)
