Abstract
This paper describes the sound of a Martian dust devil recorded by the SuperCam instrument on the Perseverance rover. The event was also captured by the rover's Navigation Camera and several sensors in the Mars Environmental Dynamics Analyzer. Analysis of the multi-sensor data and modeling reveals the dust devil's size, height, and speed. Acoustic signals of grain impacts provide quantitative information on particle density. This research demonstrates the potential of acoustic data for understanding Martian atmospheric dynamics and quantifying wind-blown grain fluxes.
