Oceanographic data for parameter estimation

Abstract Assimilation of ocean data into numerical models represents an intimate coupling of numerical ocean modeling with ocean data collection. Knowledge of climatologies, error sources and property covariances is essential and, used appropriately, represents a major step forward in being able to use inherently sparse data technologies to understand better the large scale ocean dynamics. In this chapter we will discuss several aspects of ocean data that are related to the assimilation problem. In particular, measurement techniques and their errors are discussed; assemblage of data into climatologies is described; and a form for the data covariance matrix is presented based on moored and satellite observations in the North Atlantic.
