DOI: 10.1016/j.icarus.2020.113740
Abstract: Abstract Proto-Mars growing within the solar nebula may have maintained both the hydrogen-dominated solar component and the impact degassed component enriched in H2, CH4 and CO as a proto-atmosphere. Such a proto-atmosphere would experience hydrodynamic… read more here.

DOI: 10.1029/2023gl103457
Abstract: It has been known for decades that carbon dioxide (CO2) ice clouds exist in the Martian atmosphere. According to remote sensing observations and previous modeling studies, the Martian CO2 ice crystals may be sufficiently large… read more here.

DOI: 10.1038/s41467-020-14510-x
Abstract: The atmosphere of Mars is strongly affected by the spatial and temporal variability of airborne dust. However, global dust variability within a sol (Martian day) is still poorly understood. Although short-term dynamic processes are crucial,… read more here.
