Constraining Martian Regolith and Vortex Parameters From Combined Seismic and Meteorological Measurements

The InSight mission landed on Mars in November 2018 and has since observed multiple convective vortices with both the high performance barometer low-noise seismometer SEIS that unprecedented sensitivity. Here, we present a new method uses simultaneous pressure seismic measurements of to place constraints elastic properties Martian subsurface vortex properties, while also allowing reconstruction trajectories. From data filtered (0.02–0.3 Hz) frequency band, estimate mean value η (η = E/[1 − ν2], where E is Young's modulus ν Poisson's ratio) ground region around 239 ± 140 MPa. In addition, suggest previously reported paucity observations west may be due fact harder than east, consistent geomorphological surface interpretations.
