[MIS05-05] Infrasound multi-site observation of thunders 3: preparation process for SATREPS
Keywords:Infrasound, Calibration, Remote sensing
For calibrating the both sensors, in order to evaluate precise pressure level as well as detectable frequency range, we used a chamber with a pushing/pulling mechanism on it. The infrasound multi-site observation can reveal the lightning activities as close as 100 m scale when the infrasound sensors can be installed with a mesh of 10 km scale or shorter by using the speed of sound as a precise remote-sensing scale. Recently, we also checked capability of remote-sensing in Fukui area and Kanazawa area by using real thunder signals with some other methods to compare.
In this talk, we will introduce a possibility of infrasonic remote-sensing and its calibration phase, in order to realize future disaster-mitigation studies.
