(a) SAMI3/WACCM-X TEC correlation composite at reference time 1400 MLT₀ for 2–31 January 2014 as a function of Mlat and approximate local time. The reference point is marked by a black dot. Thick black lines are correlations of 0.5, 0.7, and 0.9. (b) Line plot of TCC in Mlat at 1400 MLT₀. Dotted lines indicate the reference and conjugate Mlat, and red dot indicates the conjugate correlations. (c), (d), Same as (a), (b) except that EOF1 was removed from the TEC data before calculating the TCCs. (e) Conjugate correlation versus MLT for SAMI3/WACCM-X for each month of 2014. Lines color-coded by month as shown.
