TAO Message from the director

Welcome to the TAO project.

Dr. Michael J. McPhaden
Director, TAO Project Office

Between 1985 and 1994, the TAO Project Office of PMEL led a major international effort to instrument the entire tropical Pacific with nearly 70 deep ocean moorings.

Completed in 1994, the Tropical Atmosphere Ocean (TAO) array has enabled real-time collection of high quality oceanographic and surface meteorological data for monitoring, forecasting, and understanding of climate swings associated with El Niño and La Nina. In January 2000, the array was renamed the TAO/TRITON array in recognition of a special partnership between PMEL and the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), in which JAMSTEC will maintain several sites in the western portion of the array with its new TRITON moorings. Data and graphic displays from the TAO/TRITON array are updated every day, and the data are freely available to the research community, operational forecasting community, and the general public. The TAO Project Office also maintains pages that provide general information on El Niño and La Niña, with links to other valuable web sites describing climate forecasts, impacts, and complementary data sets.

We hope you find our pages useful and informative, and welcome suggestions on how we can improve our services.
