Regional Ionosphere Mapping By Using Neural Networks

, 2007
Regional ionosphere mapping is necessary to understand the underlying characteristics of ionosphere. In this paper, multilayer perceptrons and radial basis networks, as chosen neural network methods, are used to obtain a map of ionosphere based on a ...

Spatial Scales of Electron Density Fluctuations in the Martian Ionosphere

The Astrophysical Journal
In recent Martian ionospheric studies, the spatial scales of electron density irregularities have been computed using magnetic field measurements by treating these fluctuations as electromagnetic.

Upstream IMF Influence on Closed Magnetic Field Orientation on Mars

Geophysical Research Letters
Closed magnetic fields play an important role in plasma transport and atmospheric escape from the Martian dayside ionosphere. Leveraging in‐situ magnetic field data from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, we conduct a statistical

An astrobiological study of high latitude martian analogue environments [PDF]

, 2010
The search for life on Mars is in part reliant on the understanding of Martian environments, both past and present, in terms of what life may inhabit these environments, how this life may be preserved in the rock record, and how this rock record may be ...

Sporadic E-like Topside Layer Driven by Wind Shear in the Martian Ionosphere

The Astrophysical Journal
Ionospheric plasma density disturbances significantly affect radio wave propagation, impacting communication and planetary exploration. At Earth, sporadic E layers (Es) are commonly observed. They are characterized by thin, high-density plasma structures

Atmospheric Distribution and Escape of Odd Nitrogen on Mars

The Astronomical Journal
The total nitrogen budget in the Martian upper atmosphere is significantly contributed by the presence of odd nitrogen, mainly in the form of NO and ground-state or excited-state N.
