Direct measurements bearing on the question of the nighttime heating mechanism in the ionosphere
(Elsevier, 1967-01)
Langmuir probe measurements of electron temperature and density were made in the upper F-region on two different occasions near local midnight. The experiments were carried out at Fort Churchill, Canada, and at Wallops ...
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, ...
9. The venus ionosphere and solar wind interaction
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1977-07)
The current state of knowledge of the chemistry, dynamics and energetics of the upper atmosphere and ionosphere of Venus is reviewed together with the nature of the solar wind-Venus interaction. Because of the weak, though ...
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 ...
Energy distribution of electrons with E < 800 eV in the areomagnetosphere
(Elsevier, 1991)
The electron distribution functions measured in the neighborhood of Mars by means of the Hyperbolic Retarding Potential Analyzer (HARP) carried aboard the Phobos 2 spacecraft are presented. The measurements were carried ...
Current knowledge of Venus
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1977-05)
As an introduction to the remaining papers in this issue, a summary is given of our current knowledge of Venus, with emphasis on recent progress and on the contributions to be expected from the Pioneer Venus missions. ...
The role of relative ion flows on the thermal structure of the ionosphere
(Elsevier, 1977-11)
Calculations are presented which show that, contrary to previous suggestions, ion flow velocity differences do not have a significant effect on the thermal structure of the midlatitude topside ionosphere.
The plasma Environment of Mars
