Abstract

InSight has been measuring atmospheric pressure, wind and temperature since December 10, 2018 (around Ls=304° of Martian Year 34), 14 sols after its landing. In particular, more than one Martian year of almost continuous measurements has been obtained in 2018-2020. InSight is located in Elysium Planitia, at 4.50238°N, 135.62345°E in planetocentric coordinates (-2614 m altitude below MOLA areoid). Hence, the geophysical lander is providing the best long-duration meteorological Mars station since Viking. In this work, we review the meteorological phenomena that characterize the pressure and wind measurements at timescales larger than 1000 seconds. A subset of the meteorological observations obtained at the beginning of the mission was previously reported in [1]. The analysis is helped by comparing the results with prediction from the LMD numerical global climate model (GCM, [2]) as re-ported before landing by [3].
