Irregularities in the ionosphere

Journal of Geophysical Research, 1953
Electron clouds, both in the E and F regions of the ionosphere, have been detected at vertical incidence by means of a high-precision ionosphere sounding equipment. The clouds give rise to scattered echoes, which are delineated on an expanded sweep as individual pips, resolved out from the normal echoes.

Ionospheric irregularities and scintillation

Advances in Space Research, 2003
Abstract One of the important research objectives of the Space Weather Program is to understand the structure and formation of ionospheric plasma-density irregularities that cause scintillation of radio waves on transionospheric links. In this paper we briefly review some aspects of scintillation and irregularities: the relationship between ...

Amplification of irregularities in the ionosphere

Journal of Geophysical Research, 1966
An 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 ...

Ionospheric irregularities

Reviews of Geophysics, 1975
Ionospheric irregularities are small‐scale structures in the ionospheric plasma density generally oriented so that the plasma density variations occur rapidly across the geomagnetic field but slowly (or not at all) along the geomagnetic field. On the practical side, they play an important role in satellite communication systems [Utlaut, 1974].The scale

Ionospheric irregularities

Reviews of Geophysics, 1979
Exciting developments in the understanding of ionospheric irregularities have occurred during the 1975–1978 time frame. Advances in experimental and in theoretical and computer simulation techniques have provided the tools for this progress. Major successes have been attained in the understanding of equatorial spread F phenomena.

Robust Detection of Ionospheric Irregularities

Navigation, 2001
The approach outlined in this paper conservatively bounds the ionospheric errors even for the worst observed ionospheric conditions to date, using data sets taken from the operational receivers in the WAAS reference station network.
