Location: 7.646S, 107.688E
Data period: Mar 25, 2004 --
The eastward, northward and vertical wind data in the mesosphere
and lower thermosphere (52-122 km) estimated from the MF radar
at Pameungpeuk, Indonesia (7.65S, 107.69E). The data are stored
in the binary (SSWMA: Spaced Sensor Wind Measurement Analysis)
file named (year)(month)(day).sswma.
The SSWMA file also includes radar status data (operation frequency,
receiver amplitude and signal noise ratio etc.) and general information
about the data file itself. The upper limit of observation range was
changed from 98 km to 122 km on the nightside (17:30-06:00 LT)
as a regular operation after October 18, 2007.
There were occasionally test operations extended up to 122 km
in the period from April 19 to October 17, 2007.
For detailed information, please refer to
the document file (PDF) of the SSWMA data and
metadata.
The document file is provided by Daniel O'Connor in
Genesis Software.)
Wind data are stored in the netCDF (network Common Data From) file
named "(year)(month)(day)_pam.nc". The netCDF file includes time, range,
and wind velocity (eastward, northward and vertical components)
of the original data in the binary format (Spaced Sensor Wind Measurement
Analysis: SSWMA).
The wind data corresponding to "bad" status code (other than 0)
in the original data are replaced by missing value. For the meaning of
the status code (0-128) and detailed information, please refer to the
readme file (English,
Japanese)
and access the
metadata.
The time-height plot of eastward, northward and vertical wind data
in the mesosphere and lower thermosphere (52-122 km) estimated from
the MF radar observations at Pameungpeuk, Indonesia (7.65S, 107.69E).
File names of gif data are composed of date: (year)(month)(day)_pam.gif
(daily plot), and (year)(month)_pam.gif (monthly plot).
These plots are made using the netCDF data. Detailed description of
the netCDF data can be found in
the metadata of the netCDF data.
For daily and monthly plots, the wind data are averaged for
10 minutes and 6 hours in each height, respectively.
The 6-hour average is done if there are more than 20 valid data points
in 6-hour window. Universal time is used for time data.
Metadata for the gif data (time-height plot) is here.
