GODAE: The Global Ocean Data Assimilation Experiment

Michael J. Bell Michel LefèbvrePierre-Yves Le TraonNeville SmithKirsten Wilmer-Becker
First Paragraph

During 1996 and 1997, Neville Smith and Michel Lefèbvre developed the Global Ocean Data Assimilation Experiment (GODAE) concept (Smith and Lefèbvre, 1997). Its central idea was to conduct a 10-year international demonstration of the feasibility and utility of real-time, global ocean forecasting. The principal objectives, outlined in the GODAE Strategic Plan (IGST, 2000), were to:
1. apply state-of-the-art ocean models and assimilation methods for short-range open-ocean forecasts, for boundary conditions to extend predictability of coastal and regional subsystems, and for initial conditions of climate forecast models
2. provide global ocean analyses for developing improved understanding of the ocean and improved assessments of the predictability of ocean systems, and to serve as a basis for improving the design and effectiveness of the global ocean observing system
