Towards a global model of the martian atmosphere [PDF]

, 2003
In an effort to continuously improve the capabilities of the Martian atmospheric predictions at LMD, the GCM has been extended into thermospheric heights thus creating the first model to self-consistently couple the lower and upper regions of the ...

A New Lunar Crustal Thickness Model Constrained by Converted Seismic Waves Detected Beneath the Apollo Seismic Network

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract Analysis of conversions between compressional and shear waves is a workhorse method for constraining crustal and lithospheric structure on Earth; yet, such converted waves have not been unequivocally identified in seismic data from the largest events on the Moon, due to the highly scattered waveforms of shallow seismic events. We reanalyze the

The Ionopause at Mars and Its Correlation With Magnetic Topology and Plasma Pressure

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract We utilize Mars Atmosphere and Volatile Evolution (MAVEN) observations to investigate the ionopause boundary at Mars, the formation process of which is not yet well described. We focus on the eighth deep dip campaign (DD8), which consists of 50 consecutive orbits, and we develop an automated routine to identify ionopause boundaries in electron

Evaluating Local Ionization Balance in the Nightside Martian Upper Atmosphere during MAVEN Deep Dip Campaigns

Astrophysical Journal, 2019
Combining the Mars Atmosphere and Volatile Evolution (MAVEN) measurements of atmospheric neutral and ion densities, electron temperature, and energetic electron intensity, we perform the first quantitative evaluation of local ionization balance in the ...

An estimation of the mass dragged by the solar wind from Mars’s atmosphere in its geologic history [PDF]

Geofísica Internacional, 2001
In the past Mars had a denser atmosphere, but it lacks a magnetic field to protect the ionosphere and exosphere from the solar wind. A model for describing the loss of atmosphere in geologic time is presented.

Evolution of Water Reservoirs on Mars: Constraints from Hydrogen Isotopes in Martian Meteorites

, 2014
Martian surface morphology implies that Mars was once warm enough to maintain persistent liquid water on its surface. While the high D/H ratios (~6 times the Earth's ocean water) of the current martian atmosphere suggest that significant water has been ...

Dependence of the Martian radiation environment on atmospheric depth: Modeling and measurement [PDF]

, 2017
The energetic particle environment on the Martian surface is influenced by solar and heliospheric modulation and changes in the local atmospheric pressure (or column depth).

Stratigraphic Evidence of Backwater Morphodynamics and Lowland River Deltas in the Northern Hemisphere of Mars

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Backwater morphodynamics describe feedbacks between hydraulics and sedimentation in fluvio‐deltaic systems in the coastal backwater zone. On Earth, normalized channel belt width decreases approaching the coastline and drops sharply at the start of the backwater zone.
