Abstract F10.7, Mg II, and F30 are widely used proxies for variability in solar Extreme UltraViolet (EUV, 5–120 nm) irradiance. An alternative proxy for solar EUV variability is QEUV, an indirect measure of total solar EUV irradiance, retrieved from observations of Earth's Far UltraViolet (FUV, 120–300 nm) airglow and from empirically modeled solar EUV

Stationary flux ropes at the southern terminator of Mars [PDF]
Flux ropes have long been observed in the upper atmosphere of Venus, and more recently at Mars. Here we present magnetic field measurements of flux ropes encountered at the southern terminator of Mars by Mars Global Surveyor, and compare them to a flux ...

Due to the absence of an Earth-like dipole magnetic field, the impact of coronal mass ejections (CMEs) on the Martian nightside ionosphere differs from that on Earth and is still not well understood.

Retrieval of ionospheric profiles from the Mars Express MARSIS experiment data and comparison with radio occultation data [PDF]
Since 2005 the Mars Advanced Radar and Ionospheric Sounding experiment (MARSIS) aboard Mars Express has acquired a unique dataset on the ionosphere of Mars made up of ionospheric soundings taken by the instrument working in its active ionospheric ...

Abstract Current Mars thermospheric temperatures databases have course temporal resolution due to either a lack of data or a need to average over several orbits of data, preventing the study of short‐term, rapid changes to the Mars thermosphere. In this study, we present a new Mars thermosphere temperature database derived from individual orbits of ...

Sub-solar electron temperatures in the lower Martian ionosphere
Abstract Martian subsolar electron temperatures obtained below 250 km are examined using data obtained by instruments on the Mars Atmosphere Evolution Mission (MAVEN) during the three subsolar deep dip campaigns and a one‐dimensional fluid model.

Optimization of the Mars ionospheric radio occultation retrieval
Electron density is a key parameter to characterize Martian ionospheric structure and dynamics. Based on the ephemeris and auxiliary information derived from the Spacecraft, Planet, Instruments, C-matrix, and Events (SPICE) toolkit, we calculated the ...

Global Occurrence of Solitary Waves in the Martian Magnetosphere
Abstract This letter presents a global occurrence of bipolar solitary waves (SWs) in the Martian magnetosphere. We utilized medium‐frequency electric field measurements from October 2014 to December 2023 from the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft.

Modeling the Martian ionosphere [PDF]
The accessibility of the Martian atmosphere to spacecraft provides an opportunity to study an ionosphere that differs from our own. Yet, despite the half century of measurements made at Mars, the current state of the neutral atmosphere and its embedded ...

Martian Bow Shock and Magnetic Pile-Up Barrier Formation Due to the Exosphere Ion Mass-Loading [PDF]
Bow shock, formed by the interaction between the solar wind and a planet, is generated in different patterns depending on the conditions of the planet.
