A daytime production of photo-ionization associated with solar extreme ultra-violet (EUV) radiation increases electron density at all the latitudes as discussed by Rishbeth et al. (2000) using solar radio flux as a proxy for solar EUV. In addition to photoionization during quiet geomagnetic conditions, the varying atmosphere neutral wind modulated electron density across all latitudes (Balan et al., 2018). Compared to the high and middle latitudes, the equatorial and low-latitude ionosphere is also strongly associated with a transport process characterized by the equatorial electrojet (EEJ) strength, fountain effect and equatorial ionization anomaly (EIA). During the quiet conditions, the magnetic equator's daytime zonal electric field (EEJ strength) generated by wind dynamo
