Parallel Ocean Program (POP) Simulation

The POP model (CCSM Research Tools: CCSM3.0 POP Documentation) was run on Japan's $360 million Earth Simulator, based in Yokohama, to produce the data for the visualizations that you see here. The Earth Simulator has achieved speeds of more than 35 trillion calculations per second, and in a single day can simulate 20 to 40 years of global climate.

The POP model forms the ocean component of the CCSM (CCSM), one of the world's premier climate models. When used in CCSM the POP model is configured at relatively coarse resolution in order to be able to run long periods (hundreds or even thousands of years) required to address climate research questions. In these experiments an experimental version of POP with very high resolution is used to investigate the role of turbulent eddies in the ocean circulation.

This project is a collaboration between NCAR researchers and Japans nonprofit Central Research Institute of the Electric Power Industry (CRIEPI). More information on this project can be found here Tapping the Earth Simulator.
