Mesospheric standard observation data taken by the MU radar at Shigaraki (CSV format)

2016-07-21 17:02:00

The observation data in the mesosphere (60-100 km) taken by the MU radar at Shigaraki in Shiga Prefecture, Japan (34.86N, 136.11E, 385m MSL), which has been operated in the standard observation mode of the mesosphere. The data are stored in the CSV (Comma Separated Values) file named (year)(month)(day).(variable).csv. The variable abbreviations are uwnd, vwnd, wwnd, dpl, dpl2, dpl3, dpl4, dpl5, pwr, pwr2, pwr3, pwr4, pwr5, wdt1, wdt2, wdt3, wdt4, wdt5, pn1, pn2, pn3, pn4, and pn5 which mean zonal, meridional and vertical wind velocities, radial Doppler velocity, echo power spectral width and noise level for beam 1-5, respectively. The azimuth and zenith angles of beam 1, 2, 3, 4 and 5 are (0, 0), (0, 10), (90, 10), (180, 10) and (270, 10), respectively, in unit of degree. The numbers of the first line of each data file except for the noise level data represent altitude, and the second and below are observational date and local time (UT + 09:00), data and condition code (flag for wind data) at each altitude. The information of condition code and flag can be found in the README (http://www.rish.kyoto-u.ac.jp/mu/mesosphere/note/README_mur_mesosphere_data.html and http://www.rish.kyoto-u.ac.jp/mu/mesosphere/note/README_mur_mesosphere_wind_data.html). The noise level data consist of observation date, local time (UT + 09:00) and data. The time interval of data is the same as that of the original data, but the wind data are 1 hour average. The value of 999 contained in the wind data means missing value. These observation data are published as compressed files named (year)(month)(day)_wnd.tar.gz (wind data) or (year)(month)(day)_scr.tar.gz (other data).

If you acquire MU radar data, we ask that you acknowledge us in your use of the data. This may be done by including text such as MU radar data provided by Research Institute for Sustainable Humanosphere of Kyoto University. We would also appreciate receiving a copy of the relevant publications.
