SAMI3/climo and JPL/GIM TEC correlation composites for 2–31 January 2010 as a function of latitude and LT. The reference point is marked by the black dot. It is located on the Equator, and the reference LT varies with panel (0000, 0600, 1200, and 1800 are shown). Thick black lines indicate correlation of 0.5, 0.7, and 0.9. Thin black lines are SZA on 16 January 2010 at 10°, 20°, …, 90°.
