Of Martian atmospheres, oceans, and fossils

Icarus, 1990
Abstract Based on the absence of extensive cratering on the northern Martian plains, it is suggested that these plains were the sites of ancient oceans, 2 to 3.5 Gyr ago, with a calculatable water depth of (≥) 0.7 km. Also it appears possible to interpret the crater density counts for Chryse and the highlands as implying that Mars had a fairly dense ...

A Case Study on the Impact of Interplanetary Coronal Mass Ejection on the Martian O(1S) 557.7 nm Dayglow Emission Using ExoMars TGO/NOMAD‐UVIS Observations: First Results

Geophysical Research Letters
We report, for the first time, the impact of interplanetary coronal mass ejections (ICME) on the recently discovered O(1S) 557.7 nm dayglow emission in the Martian atmosphere.

Ice clouds in the Martian atmosphere

Journal of the Japanese Society of Snow and Ice, 2005
近年の探査衛星観測により火星の気象学的観測データの量が飛躍的に増加したことから,火星大気の氷雲の科学を定量的に論ずることが可能となってきた.火星のH2O氷雲は受動的トレーサであるため,その分布を調べることで直接観測が困難な火星大気の流れ場に関する情報を得ることができる.従来直接観測が困難であった極夜のCO2氷雲は,マーズグローバルサーベイヤーのレーザー高度計によりその存在が初めて明らかとなった.CO2氷雲は過去の火星の気候を考える上でも重要な要素である.過去に火星で実現していた温暖な気候を維持するには,厚いCO2大気にともなうCO2氷雲の温室効果が寄与していたのではないかと考えられているからである.CO2氷雲の形成過程と消散係数などの放射パラメータを調べることにより ...

Properties of Solar Wind Current Sheets in the Martian Space Environment

The Astrophysical Journal
Transient current sheets (CSs) are common magnetic structures in the solar wind that can significantly disturb the planetary space environment and cause space weather phenomena.
