Fig. 1: Acoustic data during a dusty vortex encounter.
a The pressure data during the dust devil encounter at 11.02 LTST on September 27, 2021 (Perseverance sol 215), b the SuperCam microphone sound amplitude as a function of time, c the normalised Root-Mean-Square (RMS) of the microphone signal in the 20–60 Hz bandwidth (the region containing the atmospheric signal37,38) calculated in 2-s windows, d the spectrogram of the microphone sound pressure level (calculated using a window size of 0.2 s in order to resolve the fine details in the acoustic data) showing the wind noise, the grain impacts and also the rover pump harmonic at 760 Hz, and the acoustic echo at ~6 kHz due to sound reflections from the base of the microphone37. Source data are provided as a Source Data file.
