Objective analysis is here defined to be the extraction of information from data using objective, as opposed to subjective, methods, most often via a computer program. The goals of this course are to provide a working knowledge of the basic methods of objective analysis of meteorological or oceanographic data, and to provide a critical facility for evaluating published studies utilizing these techniques. The topics include traditional mapping of data onto a regular grid as a minor subset, but mostly concentrate on techniques for extracting information from data directly, such as compositing, time series analysis, singular value decomposition, principal component analysis, and filtering. If time allows, we may touch on some new topics, such as wavelet analysis or more general statistical modeling procedures that are being used in dynamical systems analysis..
