description: Norwegian Earth System Model version 1 (medium resolution) output prepared for the CMIP5 amip experiment 

Technical details:
Production machine: Cray XT3 in Bergen (hexagon)
Model source: https://svn.met.no/viewvc/noresm/noresm/branches/noresm-ver1_cmip5-r112
Model revision number: 112
Model components: atmosphere=CAM4; ocean=MICOM; land=CLM; sea ice=CICE
Horizontal resolution: atmosphere/land=1.9x2.5 degree; ocean/sea ice=~1 degree 
Output frequency: monthly + daily + 6-hourly + 3-hourly as requested by CMIP5
Experiment type: fully coupled
Initialisation: Initial conditions are from year 1979 of experiment 3.2 historical.
Changing forcing agents: prescribed GHG concentration changes; aerosol emissions for SO4, POM and BC (see Kirkevåg et al. 2013)
Tuning parameters changed relative to the host model CAM4: rhminl=0.90 (0.91 in CAM4) reduced RH threshold for formation of low stratiform clouds; critrp=5.0 mm/day (0.5 mm/day in CAM4) maximum precipitation rate for suppression of autoconversion of cloud water; r3lc=14 um (10 um in CAM4) critical mean droplet volume radius for onset of autoconversion
