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

Notes: 

The latest version number of the text and netCDF data is different, but the contents
of both the data are the same.  

Description:

  The horizontal wind data in the mesosphere and lower thermosphere (70-112 km) 
estimated from the meteor wind radar at Serpong, one of the south-west suburbs of 
Jakarta, Indonesia (6.36S, 106.65E, 50 m MSL). The wind data are calculated from the 
original observation data with a weighting function. They are stored in the text 
file named jkt(year)(month).(resolution).txt or jkt(year)(month)(day).(resolution).txt. 
The resolution abbreviations are h2t60min00 and h4t240min00. 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 (local time), height, zonal and 
meridional winds, standard deviations of zonal and meridional winds, number of meteor 
trails used to determine the horizontal wind.
 Details are described in the metadata.
