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 ...
Twilight Mesospheric Clouds in Jezero as Observed by MEDA Radiation and Dust Sensor (RDS)
(Wiley, 2023-07)
The Mars Environmental Dynamics Analyzer instrument, on board NASA's Mars 2020 Perseverance rover, includes a number of sensors to characterize the Martian atmosphere. One of these sensors is the Radiation and Dust Sensor ...
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 ...
Convective storms in closed cyclones in Jupiter's South Temperate Belt: (I) observations
(Elsevier, 2022-07-01)
On May 31, 2020 a short-lived convective storm appeared in one of the small cyclones of Jupiter's South Temperate Belt (STB) at planetographic latitude 30.8S. The outbreak was captured by amateur astronomer Clyde Foster ...
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 ...
An intense narrow equatorial jet in Jupiter’s lower stratosphere observed by JWST
(Springer Nature, 2023-10-19)
The atmosphere of Jupiter has east–west zonal jets that alternate as a function of latitude as tracked by cloud motions at tropospheric levels. Above and below the cold tropopause at ~100 mbar, the equatorial atmosphere ...
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 ...
A long term study of Mars mesospheric clouds seen at twilight based on Mars Express VMC images
(Wiley, 2021)
We present the first systematic study of clouds observed during twilight on Mars. We analyze images obtained by the Visual Monitoring Camera (VMC) on Mars Express between 2007 and 2020. Using an automated retrieval algorithm ...
