Multi-model Meteorological and Aeolian Predictions for Mars 2020 and the Jezero Crater Region
(2021)
Nine simulations are used to predict the meteorology and aeolian activity of the Mars 2020 landing site region. Predicted seasonal variations of pressure and surface and atmospheric temperature generally agree. Minimum and ...
Radiation and Dust Sensor for Mars Environmental Dynamic Analyzer Onboard M2020 Rover
(MDPI, 2022-04-10)
The Radiation and Dust Sensor is one of six sensors of the Mars Environmental Dynamics Analyzer onboard the Perseverance rover from the Mars 2020 NASA mission. Its primary goal is to characterize the airbone dust in the ...
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 storms in closed cyclones in Jupiter: (II) numerical modeling
(Elsevier, 2022-11)
On May 31, 2020 a convective storm appeared in one small cyclone in the South Temperate Belt (STB) of Jupiter. The storm, nicknamed as Clyde's Spot, had an explosive start and quickly diminished in activity in a few days. ...
Venus cloud discontinuity in 2022: The first long-term study with uninterrupted observations
(EDP Sciences, 2023-04)
Context. First identified in 2016 by the Japan Aerospace eXploration Agency (JAXA) Akatsuki mission, the discontinuity or disruption is a recurrent wave observed to propagate over decades at the deeper clouds of Venus ...
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 ...
Winds at the Mars 2020 Landing Site. 2. Wind Variability and Turbulence
(American Geophysical Union, 2022-12)
Wind speeds measured by the Mars 2020 Perseverance rover in Jezero crater were fitted as a Weibull distribution. InSight wind data acquired in Elysium Planitia were also used to contextualize observations. Jezero winds ...
Constraints on the structure and seasonal variations of Triton's atmosphere from the 5 October 2017 stellar occultation and previous observations
(EDP Sciences, 2022)
Context. A stellar occultation by Neptune's main satellite, Triton, was observed on 5 October 2017 from Europe, North Africa, and the USA. We derived 90 light curves from this event, 42 of which yielded a central flash ...
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 ...
