| Outline of Final Research Achievements |
Using the MIROC5 climate model, we investigated the physics parameter uncertainties in the attribution of the past climate change and the future projection. At first we performed the perturbed physics ensemble (PPE) of atmospheric model to select the parameter sets for the coupled atmosphere-ocean model (AOGCM) experiments. We also performed the PPE of AOGCM. The largest parametric uncertainty source of the past temperature changes was found in the temperature responses to aerosols. In the future projection, the greenhouse gas uncertainty increased, while the aerosol uncertainty decreased.
