**Revision Number:**        242, 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/N20TRAERCN_f19_g16_0X), where X = ensemble member, X=1,2,3 for this particular set-up

**Simulation name(s):**     n1850bprpcnoc_f19_g16_spin_02
 
**Compset name used:**      N1850AERBPRP

**Model type:**             Fully coupled

**Type of run:**            Branch

**Simulation period:**      156 years

**Initialisation **         Start from N1850BPRPCNOC_f19_g16_spin_01 (which was a first attempt at this spinup simulation which no-one could create bit-reproducable results from...), branched off from date ="0251-01-01"

**Resolution:**             f19_g16= 1.9x2.5 degree atmosphere/land. Dipolar ocean/ice grid, ~ 1 degree

**Emission year(s):**       Pre-industrial (1850 emissions)

**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: ** 



**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)
