Active ionospheric experiments using high-power, high-frequency transmitters,“heaters”, to
study plasma processes in the ionosphere and magnetosphere continue to provide new …

We present the results of the radiotomographic imaging of the artificial ionospheric
disturbances obtained in the recent experiments on the modification of the midlatitude …

We report on satellite observations of plasma density enhancements (ducts) in the topside
ionosphere during four HAARP/BRIOCHE campaigns during 2009–2010. Artificial ducts …

A series of experiments were conducted with a conjunction between the midlatitude SURA
ionospheric heating facility and the multisatellite SWARM mission. We present the first …

This work presents the first results of measurements of artificial plasma disturbance
characteristics using the low‐orbit NorSat‐1 satellite, which are excited when the …

The propagation of whistler waves in a magnetized plasma containing multiple small‐scale
(100 m to 1 km) field‐aligned irregularities of enhanced electron density is considered …

We present the results of numerical simulations of artificial ducts during high‐power HF
heating performed by a novel model accounting for the effect of self‐action. This effect …

On 16 October 2009, the Detection of Electromagnetic Emissions Transmitted from
Earthquake Regions (DEMETER) satellite observed VLF whistler wave activity coincident …

New results of the DMSP satellite and HAARP digisonde observations during HF heating at
the High‐Frequency Active Auroral Program (HAARP) facility are described. For the first …

Throughout a nighttime pass of the CASSIOPE satellite at an altitude of about 1300 km
above the Sura heating facility, transmission of O-mode radiation from Sura to the enhanced …
