Expansion and Shrinking of the Martian Topside Ionosphere

, 2019
The observations made by the Mars Atmosphere and Volatile EvolutioN spacecraft in the topside (≥200 km) ionosphere of Mars show that this region is very responsive to the variations of the external (solar extreme ultraviolet flux, solar wind, and ...

A Benchmark Model for the Sunlit Martian Ionosphere: Structure, Composition, and Energetics

The Astrophysical Journal
Multi-instrument measurements of the Martian upper atmosphere and ionosphere by the Mars Atmosphere and Volatile Evolution (MAVEN) mission demand a self-consistent model capable of simultaneously solving the coupled continuity, momentum, and energy ...

Thermosphere UFKW Structures and Ionosphere Coupling as Observed by ICON

Geophysical Research Letters
Two ∼2‐week Ultra‐Fast Kelvin Wave (UFKW) events centered on days 158(203) during 2021 are investigated using winds, temperatures, plasma drifts and electron densities (Ne) measured by the Ionospheric CONnections (ICON) mission.
