Dataset of the paper Erdogan et al. (2021): Real-time monitoring of ionosphere VTEC using multi-GNSS carrier-phase observations and B-splines

The dataset comprises global Vertical Total Electron Content (VTEC) products stored in daily files (in IONEX format) and covers the days October 17 to 21, 2019. The temporal sampling of the VTEC data is 30 seconds. The spatial resolution is 5 degrees in longitude and 2.5 degrees in latitude. The dataset was generated from target parameters of the ionosphere estimated from real-time GNSS observations.
