Résumé

The four spacecraft of the Cluster mission collected a unique data set between 2002 and 2009. These data are unique not only because of their quantity but mainly because the spacecraft changed their orbits during their eight-year operational phase and therefore we have data from a large area around the Earth. We focus our analysis on observations of equatorial noise (EN) which is an intense wave emission generated by unstable ion distributions. It occurs in the inner magnetosphere and propagates close to the geomagnetic equator at frequencies between the local proton cyclotron and local lower hybrid frequencies. We use onboard analyzed data from the STAFF-SA instrument and high-resolution measurements of the WBD instrument. Furthermore we investigate connection of events in the solar wind with subsequent changes of the properties of EN such as location of the source region and the intensity of magnetic and electric fields.
