Water ice clouds in a martian global climate model using data assimilation [PDF]

open access: yes, 2011
The water cycle is one of the key seasonal cycles on Mars, and the radiative effects of water ice clouds have recently been shown to alter the thermal structure of the atmosphere.

When Barchan Dunes Move Over Craters

open access: yesGeophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract We investigate the possible outcomes of a subaqueous barchan moving over a crater‐like depression in the bed. For that, we carried out experiments where we varied the dune size, crater and grain diameters, and flow velocities. We found that subaqueous barchans can be blocked, destroyed, or pass over craters, with transitional situations, and ...

Effects of Martian Dust Storms on Ionospheric Peak Altitudes

open access: yesThe Astrophysical Journal
The effects of Martian dust storms on the atmosphere and ionosphere is one of the hot topics in Mars research. This paper reports on the effects of a local dust storm on the ionospheric peak altitude based on electron density profile observations from ...

Data assimilation for the Martian atmosphere using MGS Thermal Emission Spectrometer observations [PDF]

open access: yes, 2003
From the introduction: Given the quantity of data expected from current and forthcoming spacecraft missions to Mars, it is now possible to use data assimilation as a means of atmospheric analysis for the first time for a planet other than the Earth ...

Assimilating the Martian water cycle [PDF]

open access: yes, 2012
Water ice clouds have been shown to alter the thermal structure of the Martian atmosphere. Here we discuss the assimilation of total column water vapour and dust optical depth data from the Thermal Emission Spectrometer (TES) into the UK/LMD MGCM, and ...
