Data analysis techniques for resolving nonlinear processes in plasmas : a review

The growing need for a better understanding of nonlinear processes in plasma physics has in the last decades stimulated the development of new and more advanced data analysis techniques. Progress in this domain has greatly benefited from developments in fluid dynamics and dynamic system theory. This review lists some of the basic properties one may wish to infer from a data set and then presents appropriate analysis techniques with some recent applications. The emphasis is put on the investigation of nonlinear wave phenomena and turbulence in space plasmas.
