Seasonal trends of nighttime plasma density enhancements in the topside ionosphere
International audience In situ registrations of electron density from the Langmuir probe on board Detection ofElectro-Magnetic Emissions Transmitted from Earthquake Regions satellite are used to study spatialand temporal evolution of nighttime plasma density enhancements (NPDEs). The study introduce...
