Example of MSLP data processing for Broome Airport (location in Fig. 1). (A) Original data from January 14–19 inclusive. (B) High-pass filtered MSLP, with spikes showing the effects of the volcano generated atmospheric Lamb wave. Dashed vertical lines show the theoretical arrival times for a Lamb wave travelling from the HTHH Volcano at constant speed (320 m/s) along a great circle path. (C) Zoom of the middle panel showing only January 15, with the Lamb wave arrival well matching the theoretical arrival time.
