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 ... -
Dynamical Phenomena in the Martian Atmosphere Through Mars Express Imaging
Sánchez Lavega, Agustín María; ; ; ; ; ; ; (Springer Nature, 2024)
This review describes the dynamic phenomena in the atmosphere of Mars that are visible in images taken in the visual range through cloud formation and dust lifting. We describe the properties of atmospheric features traced ... -
