Time variation of DTEC for the events analyzed in this study. The time variation of DTEC for the nine flare events analyzed in this study during the flare occurrence. The solid black, dashed red, dashed orange, dashed blue, and dashed green lines indicate the DTEC obtained from observations, RUN-Ff, RUN-FS35, RUN-FS15, and RUN-FS10, respectively. The observed and calculated DTEC were obtained at points, where the local time was around noon when each flare event occurred. The vertical dotted lines indicate, from left to right, the flare start and end times, respectively
