Horizontal wind data in the mesosphere and lower thermosphere estimated from the meteor 
radar observations at Biak (netCDF 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 netCDF (network Common Data Form) file named 
Wb(year)(month).(resolution).nc or Wb(year)(month)(day).(resolution).nc. The resolution 
abbreviations are h2t60min00, h2t60min30, h4t60min00 and h4t60min30. For example, the 
h2t60 means weighted average of the horizontal wind with Gaussian factors over +/-2 km in 
height and +/-60 minutes in time. In this case, the number of meteors stands for that of data 
points included in the height and time window. 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 netCDF file includes time, height, zonal and meridional 
winds, standard deviations of zonal and meridional winds, and number of meteors.
