Abstract:

Coupled biologicalphysical models of marine systems serve many purposes including the synthesis of information, hypothesis generation, and as a tool for numerical experimentation. In such applications it is imperative that a rigorous model skill assessment is conducted so that the models capabilities are tested and understood. Herein, we review several metrics and approaches useful to evaluate model skill. The definition of skill and the determination of the skill level necessary for a given application is context specific and no single metric is likely to reveal all aspects of model skill. Thus, we recommend the use of several metrics, in concert, to provide a more thorough appraisal. The routine application and presentation of rigorous skill assessment metrics will also serve the broader interests of the modeling community, ultimately resulting in improved forecasting abilities as well as helping us recognize our limitations.
