Model calculations of the dayside ionosphere of Venus
(Elsevier, 1981)
Model calculations of the dayside ionosphere of Venus are presented. The coupled continuity and momentum equations were solved for O2+, O+, CO2+, C+, N+, He+, and H+ density distributions, which are compared with measurements ...
Satellite observations of new particle and field signatures associated with SAR arc field lines at magnetospheric heights
(Elsevier, 1987)
Enhancements in thermal ion densities, an oxygen dominated ring current at energies below 17 kev, and invariant latitude-limited bands of intense ELF hiss have been discovered on Stable Auroral Red (SAR) arc field lines ...
Photochemistry of planetary ionospheres
(Elsevier, 1987)
The basic photochemical processes in the upper atmospheres and ionospheres of the various bodies in our solar system (planets, moons and comets) are similar. However, there are many different factors (e.g. gas composition, ...
Time-dependent polar wind modeling
(Elsevier, 1988)
In the presence of a strong magnetic field (such as the geomagnetic field) the plasma tends to flow along the magnetic field lines, therefore in most ionospheric flow calculations the use of the gyrotropic approximation ...
An unusual SAR arc observed during ring current development, 4 August 1972
(Elsevier, 1980-01)
Measurements made from the ISIS-II spacecraft at 1400 km and ground-based measurements from New Zealand provide a detailed description of an unusual SAR arc observed at dusk on 4 August 1972, during the growth phase of the ...
A computer simulation of the midlatitude plasmasphere and ionosphere
(Elsevier, 1980-08)
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 ...
Models of Venus neutral upper atmosphere: Structure and composition
(Elsevier, 1985)
Models of the Venus neutral upper atmosphere, based on both in-situ and remote sensing measurements, are provided for the height interval from 100 to 3,500 km. The general approach in model formulation was to divide the ...
Recent advances in model calculations of the Venus ionosphere
(Elsevier, 1985)
Our understanding of the physical and chemical processes which control the behavior of the Venus ionosphere has advanced significantly during the last few years. These advances are the result of a still growing data base ...
The Venus ionosphere
(Elsevier, 1985)
Physical properties of the Venus ionosphere obtained by experiments on the US Pioneer Venus and the Soviet Venera missions are presented in the form of models suitable for inclusion in the Venus International Reference ...
