Research ArticleOpen accessIn the keywordsCoreless Winter Characteristics Observed with Global Positioning System Receivers over Antarctic and Arctic RegionsWayan Suparta, Faizatul Noor Abu Bakar, Mardina AbdullahProblem statement: The most recent warming trends occurred during the winter in Polar Regions had been attracted many researchers to study its impacts, which might affect the sensitivity of climate prediction in both regions, as well as on a global basis. Approach: The aims of this study were to observe the characteristics of coreless winter events using the GPS meteorology … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 22 Jun 2012 · 7,569 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Method to Correlate a Possible Coupling between the Upper and the Lower AtmosphereWayan Suparta, Grahame J. FraserProblem statement: Sun-earth coupling studies are one of the methods of projection to explain certain physical mechanisms of how solar activity can influence weather/climate changes. Approach: To gain insight of the above challenge, analysis of propagation delays in GPS-transmitted signals in the upper and lower atmosphere during transient events associated with intense geomagnetic storms was conducted within the Antarctic polar … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 20 Mar 2012 · 7,188 accessesView PDFCite
Research ArticleOpen accessIn the abstractMonitoring of GPS Precipitable Water Vapor During the Severe Flood in KelantanWayan Suparta, Ja’afar Adnan, Mohd. Alauddin Mohd. AliProblem statement: This study mainly discusses the possibility of PWV derived from GPS data for monitoring of water vapor changes during the severe flood due to heavy rainfall. There are two cases of heavy rainfall recorded during the winter monsoon in November 2009 at Kuala Krai, Kelantan. Approach: The first and second cases were sustained for 3 days from 4-6 … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 13 Mar 2012 · 9,166 accessesView PDFCite
