Ocean Data Assimilation DA systems are tools to synthesize ocean observation data using the numerical ocean models, and widely applied as the primary method for transforming the data into information which can be used effectively by society. Conversely, the capacity of ocean DA systems inevitably depends on the extent to which the observing system satisfies the requirements of the DA systems. If an observing system does not satisfy these requirements, the system cannot provide effective information to society, which implies observational data are abandoned without being converted into effective information. Thus, it is essential for observing systems to satisfy the requirements of the DA systems. Moreover, quantifying the impacts of observational data on products of the systems is equivalent to evaluating the impact of the observations on society.
