Experiments Designs
E0
Purpose: simulate historical climate from 1955 to 2005 in WACCM4. Forcings: HadISST used for SST; surface emissions scenario based on RCP4.5 emissions scenario from Coupled Model Inter-comparison project 5 (CMIP5); spectrally resolved solar variability; the SPARC CCMVal REF-B2 scenario recommendations applied to volcanic aerosols; Quasi-Biennial Oscillation (QBO) determined by the observed zonal wind.
E1
Purpose: simulate historical climate from 1900 to 2005 in CAM5. Forcings: HadISST used for SST; surface emissions scenario based on RCP4.5 emissions scenario from CMIP5; spectrally resolved solar variability; the SPARC CCMVal REF-B2 scenario recommendations applied to volcanic aerosols.
E2
Purpose: simulate climate from 1955 to 2005 under the influence of IPWP warming in WACCM4. Forcings: The same as E0, but HadISST used for SST, 12-month cycle climatological means from 1955 to 2005 used except IPWP (30°S to 30°N, 30°E to 180°) where based observed SST.
E3
Purpose: simulate climate from 1900 to 2005 under the influence of IPWP warming in CAM5. Forcings: The same as E1, but HadISST used for SST, 12-month cycle climatological means from 1900 to 2005 used except IPWP (30°S to 30°N, 30°E to 180°) where based observed SST.
