===== Model-run description for spin-up used in EXPECT =====

**Purpose of simulation:**  Stratospheric aerosol injection using aerosol data from Ulrike Niemeier (ECHAM simulation)

**Contact person:**         Alf Grini <alf.grini@met.no> 

**Data owner:    **         Alf Grini <alf.grini@met.no>     

**Revision Number:**        branch: projectEXPECT_cmip5-r143-1 revision: c830df6 github.com/metno/noresm

**Production computer used:** Cray XT3 in Bergen (hexagon)

**Production date:**        Winter(Spring) 2016

**Ensemble runs:**          No 

**Storage locations:**      NorStore (/projects/NS9033K/alfgr/EXPECT/NRCP85BPRPEX_MPI_20100_LWF1_2_T)

**Storage space:**          1.7 Tb at NorStore (for each ensemble member) 

**Projects:**               EXPECT

**Publications:**            

**Papers in preparation:**  

**Simulation name(s):**     NRCP85BPRPEX_MPI_20100_LWF1_2_T
 
**Compset name used:**      NRCP85XTBPRPEX

**Model type:**             Fully coupled

**Type of run:**            hybrid

**Simulation period:**      100 years (2100-2200)

**Initialisation **         Start from NRCP85BPRPEX_MPI_20100_LWF1_2 climate engineered RCP95 in EXPECT project.

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

**Emission year(s):**       RCP8.5

**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: ** Created in same way as climate engineered volcanic forcing runs, but in this run, no volcanic forcing file is given


**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)
