Coupled electrodynamics in the nighttime midlatitude ionosphere [PDF]
Geophysical Research Letters, 2001 We describe a new, self‐consistent scenario in which sporadic‐E doublets, height bands of upward‐displaced F‐layer profiles, F‐region plasma depletions, and radar backscatter plumes, are all manifestations of a coupled electrodynamical response by the nighttime midlatitude ionosphere to the presence of a traveling ionospheric disturbance (TID). We show

Space Weather, 2020 This paper presents a study on the possibility of predicting the regional ionosphere at midlatitude by assimilating the predicted ionospheric parameters from a neural network (NN) model into the Sami2 is Another Model of the Ionosphere (SAMI2).

A computer simulation of the midlatitude plasmasphere and ionosphere [PDF]
Planetary and Space Science, 1980 Abstract The main objective of this paper is to report the development of a new computer model to simulate species density, temperature and plasma flow in the ionosphere and plasmasphere. The paper provides a general description of the code for potential users.

Atmosphere, 2020 We present the results of experiments on the Earth’s lower ionosphere at mesospheric heights by creating artificial periodic irregularities (APIs) of the ionospheric plasma and simultaneous measurement of the atmospheric emission spectrum in the ozone ...

A quantitative study of ionospheric density gradients at midlatitudes [PDF]
Journal of Geophysical Research: Space Physics, 2001 The subauroral ionosphere, at the magnetic latitudes which characterize the northeastern United States, is subject to severe F region ionospheric density structuring due to the space weather effects of magnetospheric disturbance electric fields. Communications and navigation systems relying on transionospheric propagation must be able to compensate for

Mid-latitude ionosphere during two great geomagnetic storms
Annals of Geophysics, 1996 The ionospheric disturbances observed at many European ionosonde stations in association with the severe geomagnetic storms occurring on 19-20 December 1980 and 11-12 April 1981 were investigated by using the available ionospheric and geomagnetic data ...

Modern heating facility for research into the mid-latitude ionosphere
Solar-Terrestrial Physics, 2020 The development of new devices for research in physics of the upper atmosphere and near-Earth space, which can be used to carry out controlled experiments on the modification of the ionosphere by powerful short-wave radiation, is an urgent task of modern

Vertical circulation and thermospheric composition: a modelling study [PDF]
Annales Geophysicae, 1999 The coupled thermosphere-ionosphere-plasmasphere model CTIP is used to study the global three-dimensional circulation and its effect on neutral composition in the midlatitude F-layer.

Phase reversal of the diurnal cycle in the midlatitude ionosphere [PDF]
Journal of Geophysical Research: Space Physics, 2010 The typical diurnal cycle of the midlatitude F region electron density consists of a midday maximum and a midnight minimum. However, a phase reversal of this diurnal cycle has been found to occur in three distinct regions on the globe. They are the East Asian (EA) region centered around (53°N, 150°E), the Northern Atlantic (NA) region centered around ...
