Dust Lifting Through Surface Albedo Changes at Jezero Crater, Mars
(American Geophysical Union, 2023-04)
We identify temporal variations in surface albedo at Jezero crater using first-of-their-kind high-cadence in-situ measurements of reflected shortwave radiation during the first 350 sols of the Mars 2020 mission. Simultaneous ...
The sound of a Martian dust devil
(Nature, 2022-12)
Dust devils (convective vortices loaded with dust) are common at the surface of Mars, particularly at Jezero crater, the landing site of the Perseverance rover. They are indicators of atmospheric turbulence and are an ...
Reflectivity of Venus's Dayside Disk During the 2020 Observation Campaign: Outcomes and Future Perspectives
(IOP, 2022-09)
We performed a unique Venus observation campaign to measure the disk brightness of Venus over a broad range of wavelengths in 2020 August and September. The primary goal of the campaign was to investigate the absorption ...
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 ...
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 ...
