Short summary
Dayglow emission variability is expected to show a symmetric solar zenith-angle-dependent diurnal pattern as the production mechanisms are dominated by solar flux; however, this is not always the case. Our investigation reveals an imprint of equatorial electrodynamics on the neutral dayglow emission variability, as opposed to that of the solar zenith angle. This has implications in gaining a comprehensive understanding of the coupled nature of the ion-neutral behaviour in the upper atmosphere.
