Recording of Sol 38b. a, On top, the y axis of the time series ranges from −0.2 to 0.2 Pa. The spectrogram (bottom) shows bursts that extend to 300 Hz. Overlaid, with the y axis on the right, are wind speeds from MEDA booms. b, The PSD calculated for SuperCam’s microphone (in Pa2 Hz−1 for 167 s) and for MEDA pressure (in Pa2 Hz−1 for 51 min around the microphone acquisition time) and MEDA wind data (in (m s−1)2 Hz−1). The wind PSD is artificially offset by 10−2 in the y axis.
