During geomagnetically quiet and solar minimum conditions, spatial variations of the early morning thermosphere-ionosphere (TI) system are expected to be mainly governed by wave dynamics. Tostudy the postmidnight dynamical coupling, we investigated the early morning equatorial ionization anomaly (EIA) using Global-scale Observations of the Limb and Disk (GOLD) measurements of OI-135.6 nm nightglow emission and global navigation satellite system (GNSS)-based total electroncontent (TEC) maps. The EIA structures in the OI-135.6 nm emission over the American landmass resemble, spatially and temporally, those observed in the GNSS-TEC maps. The early morning EIA (EM-EIA) crests are well separated in latitude and mostly located over the middle of South America duringOctober–November. In February–April the crests are less separated in latitude and predominantly located over the west coast sector of South America. Whole Atmosphere Community Climate Model with
