The relationship between total electron content (TEC), tides phenomena and the position of moon and sun during the full moon and new moon in Selangor

摘要

Moon and sun is causative agent in the formation of tides. Tidal is a natural phenomenon caused by the gravitational force of attraction between moon and sun. The sun activity in ionospheric layer affects the variation of total electron content (TEC). This paper presents the relationship between total electron content (TEC), tidal phenomenon and the position of the moon and sun during the full moon and new moon occurrence in Selangor. The analysis was carried out from May 2013 until May 2014. The TEC were obtained by using GPS Ionospheric Scintillation and TEC monitor (GISTM) at UKM Bangi station while the tidal readings were capture from Port Klang. TEC and tidal reported consistent with a negative correlation. The gravitational effect of the new moon is equal to the full moon and based on the result, the highest tide value has been recorded on the 31 January 2014 which found to be the day which moon is closes to the earth and earth is closes to sun. This paper states the outcome of moon and sun position ratio to earth against TEC. In reference to the result obtained, the TEC value increased with the position ratio during new moon occurrence while during the full moon occurrence, the TEC value decreased with the position ratio. In regard to this analysis, it can be concluded that the TEC is directly proportional to the ratio of the position of moon and sun from earth.
