Horizontal wind data in the mesosphere and lower thermosphere estimated from the meteor 
wind radar at Biak (text format)

Description:

  The horizontal wind data in the mesosphere and lower thermosphere (70-110 km) estimated 
from the meteor wind radar observations 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.
 Details are described in the metadata.
