APPLICATION OF GPS SENSING TECHNIQUE FOR SUN-EARTH COUPLING STUDIES

 W. Suparta

ABSTRACT: Sun-Earth coupling studies is one channel projections to explain certain physical mechanisms of how solar activity exerts their influences on severe weather or changes in global climate towards improved global forecast models and space weather prediction. Measurements of atmospheric precipitable water vapour (PWV) and the ionospheric total electron content (TEC) at Husafell, Arctic vantage point from satellite at L-band signals using the Global Positioning System (GPS) technology is addressed in this paper. In this study, the lower and upper atmosphere represented by PWV and TEC respectively, is employed as a climate and solar activity parameters to enlighten Sun-Earth connection. The diurnal variation of both PWV and TEC, and its possible connection to the solar activity during the September 2008 campaign are presented. Day-to-day changes both parameters and their diurnal cycle pattern measured in this region were clearly influenced by solar activity, indicates a reasonable coupling between upper and lower atmosphere.
Keywords: GPS, sun-earth, PWV, TEC, Husafell station (HUSA).
