Short summary
Short summary
Global Positioning System (GPS) measurements of plasmasphere electron content (PEC) by Jason-2 are compared to PEC for ground-based GPS receivers in Africa. Jason-2 vertical PEC measurements corroborated the ground-based measurements, and its co-aligned slant PEC values were generally close to the ground-based slant PEC values. This correspondence indicates that the Jason-2 PEC measurements could be used to resolve some ambiguities in the determination of the ground-based PEC values.

Short summary
The lunar tide influence on the equatorial electrojet (EEJ) gets intensified around noon, primarily
during new and full Moon periods. However, the longitudinal, seasonal and solar cycle variability in
the lunar tide’s influence on ionospheric current systems is not well understood yet. In order to
investigate this, 17 years (1998–2014) of extensive magnetometer observations at four longitudinal
sectors (western American, western and eastern African, and Asian) have been analyzed.

Short summary
This investigation analyzes a chain of GPS stations in Africa in order to separate the ionosphere and plasmasphere contributions to the electron content, providing continuous temporal and latitudinal profiles during a single day. Comparisons to other GPS data analyses are also presented, indicating the influence of the plasmasphere on the determination of latitudinal variations and absolute levels, by inducing overestimates of biases. This investigation provides a basis for daily monitoring.
