An Extremely Elongated Cloud Over Arsia Mons Volcano on Mars: 2. Mesoscale Modeling
(American Geophysical Union, 2022-10)
In a previous work (Hernandez-Bernal et al., 2021, ) we performed an observational analysis of the Arsia Mons Elongated Cloud (AMEC), which stands out due to its impressive size and shape, quick dynamics, and the fact that ...
Convective Vortices and Dust Devils Detected and Characterized by Mars 2020
(American Geophysical Union, 2023-02)
We characterize vortex and dust devils (DDs) at Jezero from pressure and winds obtained with the Mars Environmental Dynamics Analyzer (MEDA) instrument on Mars 2020 over 415 Martian days (sols) (Ls = 6°–213°). Vortices are ...
The dynamic atmospheric and aeolian environment of Jezero crater, Mars
(American Association for the Advancement of Science, 2022-05)
Despite the importance of sand and dust to Mars geomorphology, weather, and exploration, the processes that move sand and that raise dust to maintain Mars' ubiquitous dust haze and to produce dust storms have not been well ...
Mars 2020 Perseverance Rover Studies of the Martian Atmosphere Over Jezero From Pressure Measurements
(American Geophysical Union, 2023-01)
The pressure sensors on Mars rover Perseverance measure the pressure field in the Jezero crater on regular hourly basis starting in sol 15 after landing. The present study extends up to sol 460 encompassing the range of ...
The diverse meteorology of Jezero crater over the first 250 sols of Perseverance on Mars
(Wiley, 2023)
NASA's Perseverance rover's Mars Environmental Dynamics Analyzer is collecting data at Jezero crater, characterizing the physical processes in the lowest layer of the Martian atmosphere. Here we present measurements from ...
Nocturnal Turbulence at Jezero Crater as Determined From MEDA Measurements and Modeling
(Wiley, 2023-08)
Mars 2020 Mars Environmental Dynamics Analyzer (MEDA) instrument data acquired during half of a Martian year (Ls 13°–180°), and modeling efforts with the Mars Regional Atmospheric Modeling System (MRAMS) and the Mars Climate ...
An Extremely Elongated Cloud Over Arsia Mons Volcano on Mars: I. Life Cycle
(AGU, 2021-03-20)
We report a previously unnoticed annually repeating phenomenon consisting of the daily formation of an extremely elongated cloud extending as far as 1,800 km westward from Arsia Mons. It takes place in the solar longitude ...
The Onset and Growth of the 2018 Martian Global Dust Storm
(AGU, 2019-05-21)
We analyze the onset and initial expansion of the 2018 Martian Global Dust Storm (GDS 2018) using ground-based images in the visual range. This is the first case of a confirmed GDS initiating in the Northern Hemisphere. A ...
Cloud morphology and dynamics in Saturn’s northern polar region
(Elsevier, 2017-07-29)
We present a study of the cloud morphology and motions in the north polar region of Saturn, from latitude ∼ 70°N to the pole based on Cassini ISS images obtained between January 2009 and November 2014. This region shows a ...
An enduring rapidly moving storm as a guide to Saturn’s Equatorial jet’s complex structure
(Nature Publishing, 2016-11-08)
Saturn has an intense and broad eastward equatorial jet with a complex three-dimensional structure mixed with time variability. The equatorial region experiences strong seasonal insolation variations enhanced by ring ...
