Field-aligned irregularity (FAI) observation data of the ionosphere taken by the MU radar (netCDF format)
ReleaseDate

Description
The field-aligned irregularity (FAI) observation data in the ionosphere between 80 km and 130 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 special observation mode of the FAI. The data are stored in the netCDF (network Common Data From) file named (year)(month)(day).(observation parameter).nc. The netCDF file includes the range, height, time, radial Doppler velocity, echo power, spectral width and noise level for each beam number and so on. The value of 1.0e+10 means missing data.
Acknowledgement
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.
