Standard observation data of the troposphere and lower stratosphere taken by the MU radar (NetCDF format)
ReleaseDate

Description
The 10-minute average observation data in the troposphere (2-20 km) taken by the MU radar at Shigaraki in the Shiga prefecture, Japan (34.86N, 136.11E, 385m MSL), which has been operated in the standard observation mode of the troposphere and stratosphere. The data are stored in the netCDF (network Common Data Form) file named (year)(month)(day).nc. The netCDF file includes the range, height, time, three components of wind velocity, radial Doppler velocity, echo power, spectral width and noise level for each beam number and so on. 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 value of 1.0e+10 means missing data. Since the screening method for original data (not published) in the previous step to derive the average wind velocity was modified, the new data version (1.02) was released on July 4, 2013.
