GFDL experiment name: CM3Z_D1_1860-2005_AllForc_H4 GFDL parent experiment name: CM3Z_Control-1860_D1 CMIP5 experiment ID: historical Initial conditions from this experiment (CMIP5 expt. 3.2-E(c) Tier 1) were taken from 01Jan0151 of the 1860 control model experiment CM3Z_Control-1860_D1. Forcing agents (7 WMGGs, tropospheric and stratospheric ozone, land use, volcanoes, solar, sulfate, black carbon, organic carbon, dust, and sea salt) vary historically from 1860-2005 following prescribed emission or concentration timeseries or internally calculated emissions. This model includes direct and indirect aerosol effects.
