Diurnal distribution of a observed IRC averaged over ± 1° MLat, b simulated IRC without tides input, c simulated IRC with tides imposed (including migrating and nonmigrating tidal), d tidal ΔIRC, e migrating tidal ΔIRC, and f nonmigrating tidal ΔIRC. Black, red, and blue curves denote the equinox, JS, and DS, respectively. The MLT resolution was 1 h, and positive values represent outward currents. The model IRC are averaged over ± 5° MLat. The linear correlation coefficients in b and c are calculated relative to the Swarm observations, and the correlation coefficients in e and f are calculated relative to the total tides effect
