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 ...
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 ...
A planetary-scale disturbance in a long living three vortex coupled system in Saturn's atmosphere
(Elservier, 2017-12-22)
The zonal wind profile of Saturn has a unique structure at 60°N with a double-peaked jet that reaches maximum zonal velocities close to 100 ms−1. In this region, a singular group of vortices consisting of a cyclone surrounded ...
The 2018 Martian Global Dust Storm over the South Polar Region studied with MEx/VMC
(AGU, 2019-08-13)
We study the 2018 Martian global dust storm (GDS 2018) over the Southern Polar Region using images obtained by the Visual Monitoring Camera (VMC) on board Mars Express (MEx) during June and July 2018. Dust penetrated into ...
Multilayer hazes over Saturn’s hexagon from Cassini ISS limb images
(Nature, 2020-05-08)
In June 2015, Cassini high-resolution images of Saturn's limb southwards of the planet's hexagonal wave revealed a system of at least six stacked haze layers above the upper cloud deck. Here, we characterize those haze ...
