Ground-Based Data Related to Midnight Airglow Enhancement Events Observed in OI 630.0 nm Airglow Lines over the Indian Longitude Sector

This dataset supports the study of midnight airglow enhancement events observed in the atomic oxygen red-line emission (OI 630.0 nm) over the Indian longitude sector. The dataset includes: OI 630.0 nm Airglow Data: From the Devasthal photometer and Silchar all-sky airglow imager, capturing the midnight airglow enhancement. Digisonde Data: Ionograms and ionospheric parameters (h'F, hmF2, foF2) from New Delhi, Ahmedabad, and Tirunelveli. TEC Data: GPS-based Total Electron Content (TEC) data from IGS station LCK4. MF Radar Wind Data: Neutral meridional wind data in the mesosphere and lower thermosphere from the Tirunelveli MF radar.
