Beam in Singapore. Beam results for the infrasound station located in Singapore using the Inferno algorithm (Garces 2013). We used the observed back azimuth and trace velocity. The upper plot is the spectrogram of signals having a high signal to noise ratio (SNR, in dB, where the noise is considered as the energy averaged over the record at each frequency band). The plot in the middle is the raw spectrogram and the lower plot corresponds to the raw infrasonic trace
