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.

The date of the detection CCYY/MM/DD relative to UTC
The time of the detection HH:MM:SS.XYZ in UTC where XYZ is the millisecond of the detection. (Note that this represents the relative accuracy of the detection, not the absolute accuracy which, in the normal mode of operation, is +/- 1 second).
The file name extension used to store the raw data for this detection (VWXYZ characters from [0-9,A-Z]).
The range of the detection in km to one decimal place (WXY.Z).
The corrected height above ground of the detection in km (WXY.Z).
The radial drift velocity of the trail in m/s (WX.YZ).
The standard deviation of the radial velocity measurement obtained from the 5 antenna pairs in the interferometer. Note that the analysis rejects data with delVr > 5.5 m/s so that this represents a limiting value for this field in the MPD file.
The zenith angle of the detection in degrees (XY.Z).
The azimuth angle of the detection in degrees measured anticlockwise from East (WXY.Z).
The number of locations this detection could have originated from (X).
The worst phase error between antennas if the measured azimuth and zenith of the detection are correct (XY.Z). Measured in degrees.
The antenna pair with the worst phase error (XY).
The receive channel used in the analysis for certain single-channel data quality tests. This is always "1" during normal operation.
The peak value of the amplitude of the meteor echo in digitizer units. This may be greater than 32767 if channel saturation has occurred (VWXYZ).
The decay time of the meteor in seconds. This is a half-life, not a 1/e time constant (.XYZ).
The entrance speed of the meteor in km/s. Bad values are characterized with "-9.99" (WX.YZ).
The signal-to-noise ratio for this meteor (X.YZ).
