Version 1.0.2 (February 2, 2012)
==================================

1. We revised several attributes for all the netCDF files in this version as follows.

  [Variable attribute]
   (1) num:long_name = "Number of observed meteors per hour"
                    -> "Number of meteors used for the weighted average of the horizontal wind"

  [Global attribute]
   (1) :History = "Data version 1.0.1"
               -> "Data version 1.0.2"

   (2) :ResouceName = "Horizontal wind data in the mesosphere and lower thermosphere 
                       estimated from the meteor wind radar at Serpong."
                   -> "Horizontal wind data in the mesosphere and lower thermosphere 
                       estimated from the meteor wind radar observations at Serpong."

   (3) :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, 
                       50m 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 jkt(year)(month).(resolution).nc or 
                       jkt(year)(month)(day).(resolution).nc. The resolution abbreviations are 
                       h2t60min00 and h4t240min00. For example, h2t60min00 means the weighted 
                       average with height and time resolutions of 2 km and 60 minutes for the 
                       data windows of +/-2 km and +/-60 minutes. The netCDF file includes time, 
                       height, zonal and meridional winds, standard deviations of zonal and 
                       meridional winds, and the number of meteor trails used to determine the 
                       horizontal wind."
                   -> "The horizontal wind data in the mesosphere and lower thermosphere 
                       (70-112 km) estimated from the meteor wind radar observations at Serpong, 
                       one of the south-west suburbs of Jakarta, Indonesia (6.36S, 106.65E, 
                       50m MSL). The wind data are calculated from the original observation data

                       of the horizontal wind."

   (4) :MaximumAltitude = "110000" -> "112000"

==================================
Version 1.0.1 (September 22, 2011)
==================================

1. We revised the time data and attribute for all the netCDF files in the version 1.0.1. 
   Detailed revisions are shown below.

 (1) We revised the time data to hours since midnight of the first day of every month.
     (In the previous version, the time data were hours since 1992-10-27 17:00:00.)

 (2) We revised the attribute of time as follows.

     time:units = "hours since 1992-10-27 17:00:00"
                 -> "hours since 1992-10-01 00:00:00 +07:00"

 (3) The global attribute ':History = "Data version 1.0.1"' was added.

2. We added netCDF files of each day.
   The time data are hours since midnight of every day.

Version 1.0 (June 19, 2011)
============================

1. 1-month netCDF data were released on 19 June, 2011.
