High-Latitude Ionospheric Irregularities.
1986Abstract : This document summarizes studies on the morphology of ionospheric structure at high latitudes. The program encompasses both theoretical and experimental investigations into this rapidly developing field. Because of the vast range of scale sizes (hundreds of kilometers to centimeters) that make up the structure, and the need for time ...

Lower ionospheric irregularities
1967This thesis is a study of the structure of that part of the ionosphere lying between 60 and 120 km. In the usual terminology the ionized parts of the atmosphere in this altitude range are called the ionospheric D and E regions, the boundary between them occurring at a height of 90 km.

Direct detection of ionospheric irregularity
Journal of Atmospheric and Terrestrial Physics, 1969Abstract A device for the direct detection of ionospheric irregularities was flown on board the 1967-38A San Marco Satellite. This device utilizes the impedance fluctuation induced in the impedance of the satellite antenna by the irregularity. Features of the device as well as typical irregularities observed along the satellite orbits are presented.

High latitude ionospheric irregularity model
Radio Science, 1974Modifications were made to the global scintillation model that was developed by Fremouw (Stanford Research Institute), to better represent recent high latitude scintillation data. These modifications were made primarily in the high latitude term of the model and include a provision for variation in the position of the scintillation boundary with ...

Ionospheric Irregularities Initiated by Planetary Waves
Cosmic Research, 2001The nonstationary process of the accumulation of ions of meteoric origin, which is caused by propagation of planetary waves at altitudes of the lower ionosphere, is considered. Based on horizontal and vertical ion drift in planetary waves, a possibility of plasma density increases by a factor of 10–20 in comparison with the background concentration is ...

Amplification of irregularities in the ionosphere
Journal of Geophysical Research, 1966An evaluation of the applicability of Martyn's amplification mechanism to the explanation of the sunset peak in the occurrence of F-region field-aligned echoes was made. The vertical velocities of the ionization, necessary for amplification of ionization irregularities by this mechanism, were estimated from measured electron number-density profiles ...

Irregularity motions in the polar ionosphere
Radio Science, 1973The frequency spectrum of a CW HF radio signal transmitted from an aircraft and propagated over a 1‐hop path inside the polar cap was recorded for about 50 nighttime hr during August 1967. Two different general types of disturbance were observed in these records: (a) a diffuse spectral broadening which was always present to some extent, even under ...
