In the original publication of this article Sun et al. (2019), “El” is missing at the beginning of the title.

The correct title should be “El Niño–Southern Oscillation effect on ionospheric tidal/SPW amplitude in 2007–2015 FORMOSAT-3/COSMIC observations”.

The original publication has been corrected.
