The review is based in a report presented by the author at the RAS Physical Sciences
Division's session in honor of Vitaly L Ginzburg's 90th birthday. It examines the current status …

Ионосфера ì это плазменный слой в верхней атмосфере, на высотах от 60 до 1000 км
(рис. 1а). Плазма в ионосфере создается ультрафиолетовым излучением Солнца, по …

Optical measurements made at the Arecibo Observatory during the 1987 heating campaign
showed large temporal and spatial variations in 630.0‐nm airglow enhancements during …

A review is given of the current state-of-the-art of experimental studies and the theoretical
understanding of nonlinear phenomena that occur in the ionospheric F-layer irradiated by …

The old problem of nonlinear effects arising due to the propagation of radio waves in the
ionosphere [I, 2] has come into play in the last 10-15 years in new ways. The introduc= tion …

This report presents the first estimates of the three‐dimensional volume emission rate of
enhanced O (1D) 6300 Å airglow caused by HF radio wave pumping in the ionosphere …

HF‐induced airglow at 630 nm was observed by the Digital All‐sky Imager, located near
Skibotn in Norway, at F‐region altitudes above the EISCAT HF facility near Tromsø on 21 …

The shape of the electron energy distribution has long been a central question in the field of
high-frequency radio-induced optical emission experiments. This report presents estimates …

The standard weak Langmuir turbulence approach to explain the artificial plasma line in
ionospheric radio modification experiments is examined. We compare solutions of a weak …

Simultaneous observations by up to three low‐light imaging stations belonging to the
Auroral Large Imaging System (ALIS) have provided the first strong evidence of high …
