Description
The horizontal wind data in the mesosphere and lower thermosphere (70-110 km) estimated from the meteor wind radar at Biak, Indonesia (1.17S, 136.10E, 45m MSL). The wind data are calculated from the original observation data with a weighting function. They are stored in the text file named Wb(year)(month).(resolution).txt or Wb(year)(month)(day).(resolution).txt. The resolution abbreviations are h2t60min00, h2t60min30, h4t60min00 and h4t60min30. For example, the h2t60 means weighted average with Gaussian factors over +/-2 km in height and +/-60 minutes in time. The min00 shows that the center of the Gaussian window corresponds to 00 minute of every hour. The intervals of the wind data are every 2 km and 60 minutes. The text file includes year, day of year, time (universal time), height, zonal and meridional winds, standard deviations of zonal and meridional winds, number of meteor trails used to determine the horizontal wind and two internal check values.
