[MTT52-02] A variety of Infrasound signals excited by meteor
Keywords:Infrasound, Meteor, Microbarograph, CTBT
Infrasound observation system sometimes detected signal generated by meteor. For instance, infrasound signal by a meteor over Kanto region on January 2013 was detected at Isumi. Isumi microbarographs recorded impulse wave due to shock wave. This result was reported at JpGU2013. By increasing detected infrasound cases by meteor, we want to extract the characteristics if the infrasound signal generated by meteor. For purposes of the CTBT, since the signal by meteor is noise, signals by meteor can be distinguished from infrasound waveform data would also contribute to the CTBT's verification regime.
