Probing the high latitude ionosphere from ground-based observations: The state of current knowledge and capabilities during IPY (2007-2009) [PDF]

open access: yes, 2008
During the International Polar Year (IPY), one area of great interest is co-coordinated, multi-instrument probing of the ionosphere at high latitudes. This region is important not only for the applications that rely upon our understanding of it, but also

Investigation of the Pre- and Co-Seismic Ionospheric Effects from the 6 February 2023 M7.8 Turkey Earthquake by a Doppler Ionosonde

open access: yesAtmosphere, 2023
During the catastrophic M7.8 earthquake in Turkey on 6 February 2023, anomalous effects were revealed in the ionosphere associated with various propagation mechanisms of seismogenic disturbance from the lithosphere up to the height of the ionosphere ...

Method to locate the polar cap boundary in the nightside ionosphere and application to a substorm event [PDF]

open access: yes, 2006
International audienceIn this paper we describe a new method to be used for the polar cap boundary (PCB) determination in the nightside ionosphere by using the EISCAT Svalbard radar (ESR) field-aligned measurements by the 42-m antenna and southward ...

A new inversion algorithm for backscatter ionogram and its experimental validation [PDF]

open access: yesAnnales Geophysicae, 2014
Oblique backscatter sounding is a powerful tool for detecting and monitoring the ionosphere continuously at a remote distance. High-frequency (HF) backscatter ionograms provide the amplitudes of backscatter signals with respect to group path or time ...
