Solar rotation effects on the Martian ionosphere [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2014
AbstractWe present a detailed investigation of the solar rotation effects on the Martian high‐latitude (~63°N–81°N) ionosphere using the electron density (Ne) data measured by Mars Global Surveyor and solar XUV and EUV fluxes measured by SOHO under high (2000–2001), medium (2003), and low (2005) solar activity conditions.

Response of photoelectron peaks in the Martian ionosphere to solar EUV/X-ray irradiance

open access: yesEarth and Planetary Physics, 2020
An important population of the dayside Martian ionosphere are photoelectrons that are produced by solar Extreme Ultraviolet and X-ray ionization of atmospheric neutrals.

Review of Venusian and Martian ionospheres

open access: yes地球与行星物理论评, 2021
The launch of Tianwen 1 marks the brand-new stage of the deep space exploration of China, which calls for the foundation of planetary science education in China. In planetary science, the ionosphere is considered to be the region of an atmosphere where a significant number of free thermal electrons and ions exist.

Variability of the Martian ionosphere from the MAVEN Radio Occultation Science Experiment

open access: yesEarth and Planetary Physics, 2019
The Martian ionosphere is produced by a number of controlling processes, including solar extreme ultraviolet radiation (EUV) and X-ray ionization, impact ionization by precipitating electrons, and day-to-night transport.

Interplanetary Magnetic Field Effect on the Location of the Martian Bow Shock: MAVEN Observations

open access: yesThe Astrophysical Journal, 2023
The Martian bow shock (BS) is generated with the mass-loading and magnetic pileup processes when the solar wind interacts with the Martian ionosphere. In this vein, the interplanetary magnetic field (IMF) frozen in the solar wind can affect the location ...

Martian Proton Aurora Brightening Reveals Atmospheric Ion Loss Intensifying

open access: yesGeophysical Research Letters, 2023
The Martian proton aurora is a distinct aurora phenomenon resulting from the direct deposition of solar wind energy into Mars' dayside atmosphere. What solar wind parameters influence the aurora activity in the short term is yet unknown, as are the ...

Variability of the Martian ionosphere

open access: yes, 2021
Historically, studying the Martian ionosphere has been difficult due to the lack of dedicated instruments for electron density measurements in the orbit of Mars.

MITM: A new Mars Ionosphere−Thermosphere Model

open access: yesEarth and Planetary Physics
In this study, we present an innovative Mars Ionosphere−Thermosphere Model (MITM), which is a time-dependent, three-dimensional (3-D) model that comprehensively represents the self-consistently coupled thermosphere and ionosphere of Mars within the ...

MoMo: a new empirical model of the Mars ionospheric total electron content based on Mars Express MARSIS data

open access: yesJournal of Space Weather and Space Climate, 2019
Aims: Several scientific landers and rovers have reached the Martian surface since the 1970s. Communication between the asset (i.e., lander or rover) and Mars orbiters or Earth antennas uses radio signals in UHF to X-band frequencies passing through the ...
