Field-aligned irregularity (FAI) observation data of the equatorial ionosphere taken by the EAR (NetCDF format)

ResourceID

Description

The field-aligned irregularity (FAI) observation data in the equatorial ionosphere taken by the equatorial atmosphere radar (EAR) at Kototabang, Indonesia (0.20S, 100.32E, 865m MSL). This FAI observation mode covers a wide altitude range from 80 to 600 km in the ionosphere (D-region (below 90 km), E-region (90-150 km), and F-region (above 150 km)). The observation 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. Details of the observation parameter are described in the EAR-FAI homepage (http://www.rish.kyoto-u.ac.jp/ear/data-fai/index.html). The value of 1.0e+10 means missing data.
