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°.

SAMI3/climo and JPL/GIM line plots of TCC versus relative LT (black) for 2–31 January 2010 at four reference local times (0000, 0600, 1200, and 1800 LT). The reference latitude is the Equator. The Gaussian fits are shown by the dashed blue lines, with the two fitted parameters shown on the bottom of each plot. Base is unitless and width is in hours LT.

The leading EOF has been removed from the TEC time series before calculating the TCCs. The reference latitude is the Equator. The Gaussian fits are shown by the dashed blue lines, with the two fitted parameters shown on the bottom of each plot. Base is unitless and width is in hours LT.

Correlations of the EOF1 and EOF2 amplitudes with F10.7 as a function of time (UTC) and month of 2010. If the correlation is significant (p < 0.050 is 95% confidence level) then a circle is included on the plot. The colors indicate the experiments SAMI3/climo (black) and JPL/GIM (blue). Thick lines and filled circles are for EOF1, while thin lines and open circles are for EOF2.
