Interplay of Gravity Waves and Disturbance Electric Fields to the Abnormal Ionospheric Variations during the 11 May 2024 Superstorm

GNSS GEO, SYISR and TIEGCM simulation data on superstorm day of 11 May 2024. GNSS GEO TECs with a temporal resolution of 30 s from 52 GNSS receivers over South Asia are provided. SYISR multiparameter observations, including electron density, line-of-sight (LOS) ion velocity, meridional winds, and vertical ion drifts over Sanya (109.6°E, 18.3°N) are provided. TIEGCM simulation results including default and contrall runs are provided.
