comment "GFDL experiment name = CM2Q-d2_1861-2000-AllForc_h1. PCMDI experiment name = 20C3M (run1). Initial conditions for this experiment were taken from 1 January of year 1 of the 1860 control model experiment named CM2Q_Control-1860_d2. Several forcing agents varied during the 140 year duration of the CM2Q-d2_1861-2000-AllForc_h1 experiment in a manner based upon observations and reconstructions for the late 19th and 20th centuries. The time varying forcing agents were atmospheric CO2, CH4, N2O, halons, tropospheric and stratospheric O3, anthropogenic tropospheric sulfates, black and organic carbon, dust, sea salt, volcanic aerosols, solar irradiance, and the distribution of land cover types. The direct effect of tropospheric aerosols is calculated by the model, but not the indirect effects." ;
