PERSPECTIVES FROM THE GLOBAL OCEAN
DATA ASSIMILATION EXPERIMENT

Abstract :
The Global Ocean Data Assimilation Experiment (GODAE) is
introduced, including a discussion of the historical basis and conceptual
framework. GODAE aims to develop a global system of observations,
communications, modeling and assimilation that will deliver regular,
comprehensive information on the state of the oceans in a way that will
promote and engender wide utility and availability of this resource for
maximum benefit to society. The overall strategy and guiding principles are
introduced and the core components discussed. The data and modeling and
assimilation systems are intended to provide infrastructure serving a broad
range of users and applications. The targeted applications include openocean forecasts, coastal and regional prediction, climate assessments and
prediction, and reanalyzes for scientific and other purposes. Both internal
and external metrics have been developed to assure the quality and
reliability of the product streams. The focus at present is on developing an
understanding and more intimate relationship with the user community.
Keywords :
Ocean, data assimilation, observations, prediction.

Introduction
The concept of a Global Ocean Data Assimilation Experiment (GODAE)
emerged from the Ocean Observation Panel for Climate (OOPC) in 1997
and derived from concern that attracting the investment for an adequate
long-term global ocean observing system depended upon a clear
demonstration of the feasibility and value of such a system (Smith and
Lefebvre, 1997). Using the First GARP (Global Atmospheric Research
Program) Global Experiment (FGGE) as a model, OOPC proposed GODAE
as an experiment in which a comprehensive, integrated observing system
would be established and held in place for several years and the data
