Parameters of the Infrasound Signal Generated by a Meteoroid over Indonesia on October 8, 2009

The basic parameters (delay time, celerity, duration, oscillation period, and amplitude) of the infrasound signal recorded by 17 stations are statistically analyzed as a function of the horizontal distance between the Indonesian superbolide total radiated energy and the infrasound station location....

Description
Summary:The basic parameters (delay time, celerity, duration, oscillation period, and amplitude) of the infrasound signal recorded by 17 stations are statistically analyzed as a function of the horizontal distance between the Indonesian superbolide total radiated energy and the infrasound station location. Fitting dependences of signal parameters on distance are given. Correlation diagrams are constructed and analyzed. The basic parameters of the meteoroid, the corrected value of the infrasound signal celerity, and the average tropospheric-stratospheric wind velocity are estimated.
