Abstract High-frequency seismic data on Mars are dominated by wind-generated lander vibrations, which radiated partially to the subsurface. Autocorrelation functions (ACFs) of filtered between 1 and 5 Hz show clear phases at ∼1.3, ∼2.6, ∼3.9 s. Daily temporal changes their arrival times (dt/t) correlate well with daily ground temperature, ∼5% variation ∼50 min apparent phase delay. The followin...
