Abstract

This paper presented the diurnal and seasonal variability of total electron content (TEC) data recorded at equatorial latitude, Langkawi station (6.18°N. 99.51°E) and Unimas station (1.46°N. 110.4°E). The analysis has been done extensively at different latitude in order to understand the latitudinal variation of TEC in different latitudes and longitudes. The TEC data in both northern and southern Malaysia region are examined by using the NovAtel GSV4004B GISTM receiver at two stations. This analysis cover in a period of 2015 from January to December and it is presented in three seasons which are equinox (March, April, September, and October), summer solstice (May, June, July, and August) and winter solstice (November, December, January, and February). The diurnal variations shown that the maximum TEC occurred between 0600–0800 UT (1400–1600 LT), and then gradually fall after sunset and minimum during dawn. For the seasonal variation, the result shown that TEC was maximum during equinox month (60 TECU for Langkawi station and 57 TECU for unimas station) and minimum during summer solstice (44 TECU for Langkawi station and 46 TECU for unimas station), with intermediate values during winter solstice (53 TECU for Langkawi station and 50 TECU for unimas station). The diurnal and seasonal variation of TEC for both stations has been carried out and found that Langkawi station experiences higher value of TEC than Unimas station with a difference of 5 TECU for diurnal variation and approximately 3 TECU for seasonal month.
