Recent advances in planetary ionospheres
Space Science Reviews, 1996Recent results on the ionospheres of various planets are reviewed. In view of the large amount of data now available on Venus, much of the work relates to this planet. The outer planets received somewhat less attention partly due to lack of measurements in the post-Voyager era.

Current Systems in Planetary Magnetospheres and Ionospheres
Space Science Reviews, 2010The interaction of planets with the solar wind produces a diversity of current systems, yet these can be classified into only a few different types, which include ionospheric currents, currents carried by magnetospheric boundaries like the magnetopause or ionopause, magnetotail currents, and currents flowing inside the magnetospheres, like ring ...

Electric currents in E-like planetary ionospheres
Planetary and Space Science, 1990In this paper an MHD approach is used to consider the conduction of electric current in a lightly ionized gas, taking into account the gradients of pressure in the ion and electron gases, in addition to the electric field. The coefficients of electrical conductivity are found for each driver of current.

Radio Occultation Experiment for Probing Planetary Ionospheres
2019 URSI Asia-Pacific Radio Science Conference (AP-RASC), 2019Radio occultation (RO) is an important measurement technique for studying planetary atmospheres. It is based on the measurement of the frequency shift of the received radio signal from the spacecraft, caused by the bending of radio waves in the atmosphere.

Hydrogen collisions in planetary atmospheres, ionospheres, and magnetospheres
Planetary and Space Science, 2008Hydrogen is the most abundant element in the universe. Molecular hydrogen is the dominant chemical species in the atmospheres of the giant planets. Because of their low masses, neutral and ionized hydrogen atoms are the dominant species in the high atmospheres of many planets.

Planetary waves in rotating ionosphere
Plasma Physics Reports, 2008The problem of propagation of ultralong planetary waves in the Earth’s upper atmosphere is considered. A new exact solution to the MHD equations for the ionosphere is obtained in spherical coordinates with allowance for the geomagnetic field and Earth’s rotation.

Planetary wave effect on ionospheric absorption
Journal of Atmospheric and Solar-Terrestrial Physics, 1998Abstract A relationship is examined between quasi-periodic fluctuations in absorption data at ionospheric altitudes and wave perturbations in wind data at tropospheric, stratospheric and lower mesospheric heights at Indian latitudes. The spectral analyses using Maximum Entropy Method (MEM) reveal almost the same band of periodicities in both the ...

Traveling planetary scale waves in the ionosphere
Journal of Atmospheric and Terrestrial Physics, 1975Abstract From an analysis of long distance received daytime VLF phase data over three transmission paths spanning a total of 160° of longitude, and from lower stratospheric radiance data from the SIRS instrument on the Nimbus IV weather satellite, traveling planetary scale waves are shown to exist at about 70 km for the 1970/1971 winter.

On the planetary ionospheric vortex electric fields
Advances in Space Research, 2008Abstract The paper presents a physical mechanism of large-scale vortex electric field generation in the ionospheric E- and F-layers. It shows that the planetary-scale, synoptic short-period (from several second to several hours) and fast processes (with propagation velocity higher than 1 km/s) produce a planetary-scale internal vortex electric field.
