Abstract

This study investigates the role of gravity waves (GWs) in modulating nighttime ionospheric irregularities over South Asia, particularly Pakistan. Using data from ionosondes, GNSS receivers, and satellite observations (e.g., TIMED/SABER, COSMIC), we identify gravity wave signatures and correlate them with sporadic E layers, spread F phenomena, and equatorial plasma bubbles (EPBs). Results suggest a strong link between upward-propagating GWs and the generation of ionospheric irregularities, especially during post-sunset hours. This modulation is crucial for understanding GNSS signal disruptions and improving regional space weather prediction models.
