Computer Modelling

On-line computer-modelling book at Oak Ridge national laboratory ( We have embarked upon this exposition of ocean models with three goals: (a) to outline the hydrodynamic and numerical foundations upon which the current ocean models rest; (b) to provide the initial tools for beginners (and even for more advanced modelers) to simulate and forecast the oceanic environment; and (c) to provide a general overview for technical people in all fields on the current approaches in modeling the circulation and thermodynamic state of the ocean.

Computational Education Project ( CSEP is an electronic book for teaching Computational Science and Engineering. The intended audience are students in science and engineering at the advanced undergraduate level and higher. Tutorials for freely available networking and visualization software are included and have attracted a range of users, including high-school students and people from the commercial sector.

ECCO Model: Estimating the Circulation and Climate of the Ocean ( ECCO is a consortium formed by a group of scientists intending to bring ocean state estimation from its current experimental status to that of a practical and quasi operational tool for studying large-scale ocean dynamics, designing observational strategies, and examining the ocean's role in climate variability.

Mercator Project: North Atlantic and Global Maps and Forecasts ( - The Public Interest Group (GIP) Mercator Ocean was founded in April 2002 with a brief from its six member organizations to set up an operational system for describing the state of the ocean, an integral part of our environment, at any given time and at any place on our blue planet. Input for the Mercator system comes from ocean observations measured by satellites or in situ observations through measurements taken at sea. These measurements are "ingested" (assimilated) by the analysis and forecasting model. The assimilation of observation data in a model is used to describe and forecast the state of the ocean for up to 14 days ahead of time.

MIT Climate Model ( a collaboration between scientists in the Center for Global Change Science of MIT, to develop a state-of-the-art model of the atmosphere and ocean for study of the climate of the Earth.

Texas A&M University Links to Ocean Circulation Modeling Projects ( - There is information available via the WWW about quite a few ocean circulation modeling projects, including in some cases the source code for the models themselves. Here's a list of the ones I know of, a brief description of the site, and information as to the availability of the model. The models range from primitive equation to quasi-geostrophic, from level to layer, from regional to global, from single- to multi-processor, and from well- to poorly-documented.
