Figure 2
Results from AIC algorithm validation. \(-\Delta \mathrm {AIC}\) daily plots from 22 February 2011 (DOY 53) to 14 March 2011 (DOY 73). This figure represents a reproduction of Fig. 6 (panels d, e, and f) by Heki and Enomoto27 but obtained with our own AIC algorithm using the same values of \(\Delta t\) , \(Th_{\mathrm{A}}\) and \(Th_{\mathrm{R}}\) (\(\Delta t\) = 60 min, \(Th_{\mathrm{A}}\) = 3.5 TECU/h, \(Th_{\mathrm{R}}\) = 75%). vTEC data used for this figure are derived from measurements made by the GEONET receiver 3009 related to the GPS satellite 15.
