Short summary
Higher total electron content (TEC) day-to-day variations during the daytime than at night were observed for all years. The diurnal variation shows observed
TEC (OBS-TEC) rising rapidly from a minimum just before sunrise at 03:00–05:00 LT (∼2 TECU) in 2011, 04:00–05:00 LT (∼3 TECU) in 2012, 03:00–05:00 LT in 2013 (∼3 TECU) and 03:00–05:00 LT in 2014 (∼3 TECU). OBS-TEC is found to increase to a broad daytime maximum at 00:12–00:16 LT for all years before falling to a minimum after sunset.
