Multi-Scale Simulator for the Geoenvironment (MSSG), which is a coupled non-hydrostatic atmosphere-ocean-land model, has been developed in the Earth simulator Center. Outline of MSSG is introduced and characteristics are presented. After optimizing computational performance of MSSG, performance analysis has been performed on the Earth Simulator. As the results of optimization, ultra high performance with MSSG has been achieved. Computational performance of the coupled non-hydrostatic atmosphere-ocean-land model has attained 52-55% of theoretical peak performance. Furthermore, results from preliminary validations including forecasting experiments are presented.
