Abstract

Electron density irregularities in the ionosphere that cause rapid fluctuations in radio signals or scintillation has been studied using the Low-Latitude Ionospheric Tomography Network. The network uses Ionospheric Tomography System (ITS) receivers to retrieve VHF and UHF scintillation data from August 2008 to February 2011. Amplitude scintillation, which mostly occurred at the equatorial anomaly peak, varied with local time, solar activity and magnetic activity. Moreover, night-time scintillation occurred predominantly around local midnight (2100-0200 LT), while most of the daytime scintillation occurred at 0900-1500 LT. Generally, the scintillation occurred under quiet magnetic condition and the occurrence increases as the solar activity increases. © 2006-2015 Asian Research Publishing Network (ARPN).
