Latitude Oscillations of Zonal Mean Total Electron Content and Super-Fountain Effects Provided from Global GNSS Stations

Abstract. Seasonal and latitude oscillations of equatorial ionization anomaly (EIA) were investigated by zonal mean total electron content (TEC) provided from global gridded GNSS data from 1999 to 2017. Maximum monthly zonal mean TEC values showed NH spring equinox’s value is higher than fall's. Some fluctuations are observed due to upward planetary wave propagation in equinoxes and winter especially in low solar activity. Two cases of super-fountain effect were also clearly detected on zonal mean TEC.

Short summary
The ionosphere is one of the important layers of the atmosphere that affect the transmission of radio waves. In equatorial ionosphere anomaly (EIA) the lifted plasma diffuses downward on both sides of magnetic equator and creates two crests. The values of monthly zonal means of TEC are separated and shows fluctuations due to upward planetary wave propagation in equinoxes and winter. In addition, two cases of super-fountain effect (contain Halloween solar storm) were detected on zonal mean TEC.
