Planetary ionospheres

open access: yesSpace Science Reviews, 1988
Experimental results on the ionospheres of Venus, Mars, Jupiter, Saturn, and Uranus are reviewed, especially from space missions like Pioneer Venus, Viking-1, and -2, Pioneer-10 and -11, and Voyager-1 and -2. Our emphasis has been on Venus, since most of

Photochemistry of planetary ionospheres [PDF]

open access: yesAdvances in Space Research, 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.

Transplanet: A web service dedicated to modeling of planetary ionospheres

open access: yesPlanetary and Space Science, 2019
International audienceWe present a new web service (http://transplanet.irap.omp.eu/) dedicated to the modeling of planetary iono-spheres. Thanks to the development made for IRAP ionospheric model IPIM, it uses a unified description of the different ...

Spectroscopy and photochemistry of planetary atmospheres and ionospheres: Mars, Venus, Titan, Triton and Pluto

open access: yes, 2019
The chemical composition of any planetary atmosphere is of fundamental importance in determining its photochemistry and dynamics in addition to its thermal balance, climate, origin and evolution.

Dissociative Recombination in Planetary Ionospheres

open access: yes, 1992
Ionization in planetary atmospheres can be produced by solar photoionization, photoelectron impact ionization, and, in auroral regions, by impact of precipitating particles.

Planetary Ionospheres and Magnetospheres

open access: yes, 2008
We begin this chapter with a detailed review of the ionization and recombination processes in a planetary ionosphere, as exemplified by the ionosphere we know the most about, that of the Earth. We then extend the discussion to the ionospheres of Mars and Venus, and examine atmospheric loss mechanisms.

Models of Planetary Ionospheres

open access: yes, 1973
The distribution of charged particles (electrons and ions) in a planetary ionosphere is governed by the equation of continuity $$\frac{{\partial N}}{{\partial t}} = q - L(N) - \nabla \cdot (Nv)$$ (6-1) A steady state situation (∂N/∂t = 0) can often be assumed, except near sunrise and sunset or during other rapidly varying situations such as a
