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

Note:

  SINCE SEVERAL TEXT FILES IN THE PREVIOUS VERSION CONTAIN DATA GAPS AND 
INCORRECT DATA, WE REPLACED THEM WITH CORRECT ONES. PLEASE DO NOT USE THE 
WIND DATA DOWNLOADED FROM THIS HOMEPAGE BEFORE AUGUST 26, 2011 FOR ANY 
ANALYSES AND PUBLICATIONS. 

Description:

  The horizontal wind data in the mesosphere and lower thermosphere 
(70-110 km) estimated from the meteor wind radar at Kototabang, Indonesia 
(0.20S, 100.32E, 865m MSL). The wind data are calculated from the original 
observation data with a weighting function. They are stored in the text 
file named Wk(year)(month).(resolution).txt or 
Wk(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.


Data revision:

  Data version 1.1.1 was released on October 18, 2011. In this version, 
we fixed several text files which contain data gap and incorrect data.
