| comment = 'GFDL experiment name = CM2Q-d2_1PctTo4x_j1. PCMDI experiment name = 1%to4x (run1).
Initial conditions for this experiment were taken from 1 January of year 41 of the 1860 control
model experiment named CM2Q_Control-1860_d2. In the CM2Q-d2_1PctTo4x_j1 experiment atmospheric
CO2 levels were prescribed to increase from their initial mixing ratio level of 286.05 ppmv
at a compounded rate of +1 percent per year until year 140 (the point of quadrupling).
CO2 levels were held constant at 1144.21 ppmv from year 141 through the end of the 300 year
long experiment. For the entire 300 year duration of the experiment, all non-CO2 forcing agents
(CH4, N2O, halons, tropospheric and stratospheric O3, tropospheric sulfates,
black and organic carbon, dust, sea salt, solar irradiance, and the distribution of
land cover types) were held constant at values representative of year 1860.'
