TL;DR: In this paper, the ground signature of a flux transfer event (FTE) has been observed using the STARE radar system, which has the potential for making observations pertinent to identifying and studying the ionospheric signatures of FTE.

TL;DR: The GEROS-ISS mission objectives are determined, the determination of the altimetric sea surface height of the oceans and of the ocean surface mean square slope are derived using reflected GNSS signals (GNSS reflectometry, GNSS-R).

TL;DR: In this article, the experiments performed up to mid 1984 with the heating facility at Ramfjordmoen near Tromso, Norway, are summarized, including D -region modification, polar electrojet modulation at VLF, ELF and ULF frequencies, excitation of E-region small-scale irregularities and of F -region small and large scale irregularities, anomalous absorption of HF wave on long and short time scales.

TL;DR: The G-TERN will implement the interferometric GNSS reflectometry concept, from a single satellite in near-polar orbit with capability for 12 simultaneous observations, and uses the full GNSS available bandwidth to improve its ranging measurements.

TL;DR: In this paper, the results obtained using the Fresnel inversion method were compared to results obtained with the traditional geometrical optics inversion approach and to numerical weather prediction data.
