 | Observation data of meteor traces in the mesosphere and lower thermosphere taken by the meteor wind radar at Biak (text format)
|
| |
| Description: |
| The original observation data of meteor trails and its radial velocity in the mesosphere and lower thermosphere (70-110 km) taken by the meteor wind radar at Biak, Indonesia (1.17S, 136.10E, 45m MSL). The data are stored in the text file named mp(year)(month)(day).biak.mpd. The lines 1-29 represent the file header which contains the site location (latitude, longitude), height resolution, the number of range gate number and radar status (operation frequency, antenna coordinate, record length and phase offset etc.). The line 30 is each parameter name (‘Date’, ‘Time’, ‘File’, ‘Rge’, ‘Ht’, ‘Vrad’, ‘delVr’, ‘Theta’, ‘Phi0’, ‘Ambig’, ‘Delphase’, ‘ant pair’, ‘IREX’, ‘amax’, ‘Tau’, ‘vmet’, and ‘snrdb’) while the lines 31 and below are date, time (universal time) and observation data. |

| Name: Meteor wind radar at the Biak observatory |
| Description: The meteor wind radar at Biak, Indonesia (1.17S, 136.10E, 45m MSL) has been operated since May 31, 2011, and measures the reflected VHF radio wave from an ionized meteor trail at 70-110 km altitude produced by interaction between a meteorite and the neutral atmosphere. Since the meteor trail drifts following the motion of the ambient neutral atmosphere, radial wind velocity can be determined by using a Doppler signal. Basic parameters of this meteor radar system consist of operating frequency (33.32 MHz), transmitter of peak power (~12 kW), and pulse width (13.3 micro sec). The antenna system is typically composed of three-element Yagis for transmission and five 2-element Yagis for reception. The latter compose an interferometer for accurate determination of echo arrival angle. |
