OFES OGCM for the Earth Simulator

OFES^[1] and the Earth Simulator enable us to perform decadal integrations of eddy resolving ocean simulations in the world ocean. The Japan Agency for Marine-Earth Science and Technology (JAMSTEC) promotes OFES research project and collaborates with several research groups. This site provides access service of the outputs from OFES quasi-global eddy-resolving simulation at a horizontal simulation of 0.1 degree. The OFES outputs may be used for research purposes for free under the terms and conditions.

Using OFES ver. 1, the climatological simulation was spun-up for 50 years from observation data without motion (see details in Masumoto et al., 2004). Following the climatological simulation, the hindcast simulation has been conducted from 1950 (see details in Sasaki et al., 2008). The period of simulation is extended to the present year.

1. ^ OFES: Based on the Modular Ocean Model ver.3 (MOM3), developed by GFDL/NOAA, we have developed an OGCM code (OFES: OGCM for the Earth Simulator) optimized for massively-parallel computations on the Earth Simulator.

How to Access

The outputs from OFES ver. 1 are distributed through GrADS Data Server. Use DODS-enabled applications, such as GrADS or NCL for visualization and NCO (ncks) to slice and download data. Meta data^[2] is displayed when accessed with a web browser.

2. ^ Using DODS applications, the vertical direction of 3D variable is upside-down with the false unit of “mbar” (z = 54 for the surface data).

Available Data

• Climatological simulation (Monthly mean from 41yr to 50yr)
• Hindcast simulation from 1950 to two year ago (Monthly mean). Regarding to use the latest data, please contact to JAMSTEC.
