Papers in preparation: Sand et al. (submitted)
Simulation name(s): N_r99PDX, where X = yr116, noBCyr116, noBCdepyr116
Compset name used: NAER2000
Model type: Fully coupled
Type of run: Initial
Simulation period: 92 years
Spin-up period: 116 years
Ensemble runs: No
Resolution: f19_g19 = 1.8×2.5
Emission year(s): 2000 (aerosols and precursors)
Emission inventories IPCC AR5
Frequency for output: Monthly
Active/changing forcing agents: In principle, direct and indirect (1. & 2.) effects by anthropogenic SO4, POM and BC, but aerosols were run offline (CAM4-Oslo aerosols do not affect the model meteorology, only prescribed aerosols and CDNC from CAM4 )
Tuning parameters which are changed relative to the host model CAM4:
rhminl: 0.90 lower RH threshold for formation of low stratiform clouds (0.91 in CAM4)
critrp: 5.0 mm/day maximum prcipitation rate for suppression of autoconversion of cloud water (0.5 mm/day in CAM4)
r3lc: 14 um critical mean droplet volume radius for onset of autoconversion (10 um in CAM4)
