Multiscale Simulation Research Group

Group Leader
Keiko Takahashi (Profile)

A coupled non-hydrostatic atmosphere-ocean model has been developed, capable of multiscale-multiphysics simulation according to purpose or use. The coupled model has been optimized for Earth Simulator, and has reached a peak computational efficiency of 55%.

Geophysical Fluid Simulation Research Group

Atmosphere and Ocean Simulation Research Group

Group Leader
Wataru Ohfuchi (Profile)

The Geophysical Fluid Simulation Research Group conducts high-resolution and large-scale simulations of the ocean and atmosphere to understand the oceanic roles in global climate and its variability.

OFES Data Access
Earth Simulator Center has started a public access service to outputs of an ultra-high resolution oceanic simulation, which is conducted on Earth Simulator using OFES (OGCM for Earth Simulator). Three-dimensional data of velocities, temperature, and salinity fields and two-dimensional data including sea surface height, which represent well climatological oceanic fields.

Simulation Technology Application Research Group

Group Leader
Toshiyuki Asano

The Simulation Technology Application Research Group is active in application of large-scale numerical simulations to various industries, and in development of the simulation technologies through collaboration research with universities and companies.

Observing System Research and Ensemble Data Assimilation Development Research Team

Observing System Research and Ensemble Data Assimilation Development Research Team

Team Leader
Nobumasa Komori

We develop ensemble-based assimilation systems of atmospheric, cryospheric and greenhouse gas data and to conduct observing system research in order to evaluate observations and to study predictability. This is a cross-cutting team among the Earth Simulator Center and several programs of the Research Institute for Global Change, conducted in cooperation with researchers at the University of Maryland and at Doshisha University.

ALERA
AFES-LETKF experimental reanalysis of atmospheric data.
This dataset is produced under the collaboration among the Japan Meteorological Agency, Japan Agency for Marine-Earth Science and Technology, and Chiba Institute of Science.
