abstract = "The main purpose of this paper is to study the response of the
ionospheric F-region using GPS-TEC measurements at equatorial and
low latitude regions over the Brazilian sector during an sudden
stratospheric warming (SSW) event in the year 2006. In this work,
we present vertical total electron content (VTEC) and phase
fluctuations derived from GPS network in Brazil. The continuous
wavelet transform (CWT) was employed to check the periodicities of
the \∆VTEC during the SSW event. The results show a strong
decrease in VTEC and \∆VTEC values in the afternoon over
low latitudes from DOY 0539 (during the SSW event) mainly after
the second SSW temperature peak. The ionospheric \∆VTEC
pattern over Brazilian sector shows diurnal and semidiurnal
oscillations during the 2006 SSW event. In addition, for the first
time, variations in \∆VTEC (low latitude stations) with
periods of about 0208 day have been reported during an SSW event.
Using GPS stations located in the Brazilian sector, it is reported
for the first time that equatorial ionospheric irregularities were
not suppressed by the SSW event.",
