comment = "GFDL experiment name = CM2Q_Control-1860_d2. PCMDI experiment name = PIcntrl (run1). Initial conditions for this experiment were derived from a multi-step process. First, an atmosphere + land surface model was spun up with forcing agents at levels representative of the late 20th century. Second, the spun up atmosphere + land surface model was coupled to an ocean + sea ice model. Initial conditions for sea ice, ocean potential temperature and salinity were derived from late 20th century observations. Forcing agents consistent with year 1860 were applied to the coupled model which was integrated for a ~300 year adjustment period. Year 1 of the archived CM2Q_Control-1860_d2 experiment data begins at the end of this adjustment period. CM2Q_Control-1860_d2 forcing agents representative of conditions circa-1860 include the well-mixed greenhouse gases (CO2, CH4, N2O), tropospheric and stratospheric O3, tropospheric sulfates, black and organic carbon, dust, sea salt, 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." ; realization = 1 ; experiment_id = "pre-industrial control experiment" |
