Abstract: Abstract In situ satellite observations of geospace phenomena provide insight into the structure and dynamics of the highly variable plasma environment of the Earth. Multi-spacecraft missions such as Cluster and THEMIS allow to study spatiotemporal correlations of dynamical plasma variables, in addition to the polarization information accessible through vector observables and multi-instrument measurements. This chapter reviews single-spacecraft polarization methods as well as multipoint techniques. In both categories common aspects of boundary analysis, gradient estimation, and wave identification are emphasized. Combinations of the two approaches are particularly important when less than four spacecraft orbit in close configuration, e.g., in the case of the upcoming Swarm constellation designed to study the geomagnetic field, the ionosphere, and inner magnetosphere. Key analysis concepts and approaches can be comprised into a coherent framework that is expected to facilitate model comparison and error analysis.
