EMIRS Observations of the Aphelion‐Season Mars Atmosphere [PDF]
Geophysical Research Letters, 2022 Thermal infrared spectra taken by the Emirates Mars Infrared Spectrometer (EMIRS) on‐board the Emirates Mars Mission (EMM) spacecraft are well suited for the retrieval of surface temperatures, the atmospheric temperature profile from the surface to ∼40 ...

A three-dimensional atmospheric dispersion model for Mars
Progress in Earth and Planetary Science, 2021 Atmospheric local-to-regional dispersion models are widely used on Earth to predict and study the effects of chemical species emitted into the atmosphere and to contextualize sparse data acquired at particular locations and/or times. However, to date, no

The Atmospheres of Mars and Venus [PDF]
Annual Review of Astronomy and Astrophysics, 1971 Of all the planets which may exist in the Universe, only nine have been studied by man. As a result, one cannot classify planets with the same confidence that one has in classifying stars; there is no theory of planetary evolution comparable in development to the theory of stellar evolution.

Brief communication: Lower-bound estimates for residence time of energy in the atmospheres of Venus, Mars and Titan [PDF]
Nonlinear Processes in Geophysics, 2021 The residence time of energy in a planetary atmosphere, τ, which was recently introduced and computed for the Earth's atmosphere (Osácar et al., 2020), is here extended to the atmospheres of Venus, Mars and Titan.

Detection of Martian dust storms using mask regional convolutional neural networks
Progress in Earth and Planetary Science, 2022 Martian dust plays a crucial role in the meteorology and climate of the Martian atmosphere. It heats the atmosphere, enhances the atmospheric general circulation, and affects spacecraft instruments and operations.

Influence of Magnetic Fields on Precipitating Solar Wind Hydrogen at Mars
Geophysical Research Letters, 2022 Solar wind protons can interact directly with the hydrogen corona of Mars through charge exchange, resulting in energetic neutral atoms (ENAs) able to penetrate deep into the upper atmosphere of Mars.

What Is the Radiation Impact of Extreme Solar Energetic Particle Events on Mars?
Space Weather, 2023 Solar Energetic Particles (SEP) are one of the major sources of the Martian radiation environment. It is important to understand the SEP‐induced Martian radiation environment for future human habitats on Mars.

Earth and Planetary Physics, 2020 Forbush decreases are depressions in the galactic cosmic rays (GCRs) that are caused primarily by modulations of interplanetary coronal mass ejections (ICMEs) but also occasionally by stream/corotating interaction regions (SIRs/CIRs).
