Monthly and seasonal diurnal means of hourly VTEC variation. The top panels (a, b) show the monthly and seasonal variation of the VTEC over Nazret (station number 4) during the low solar activity (2009), and the bottom panels (c, d) show the monthly and seasonal variation of the VTEC over Arba Minch (station number 7) during the high solar activity (2012) phase.
