Phase scintillations at the polar ionosphere
A dual-frequency GPS Ionospheric Scintillation and TEC Monitor (GISTM) receiver, GSV4004B, has been installed at Alert, Canada (82.48° N, 297.75° E, corresponding to 86.95° N, 155.77° E geomagnetic coordinate) since May 2008 to study the ionospheric variability at a high-latitude location. This GIST...

| Summary: | A dual-frequency GPS Ionospheric Scintillation and
TEC Monitor (GISTM) receiver, GSV4004B, has been installed
at Alert, Canada (82.48° N, 297.75° E, corresponding to 86.95° N,
155.77° E geomagnetic coordinate) since May 2008 to study the
ionospheric variability at a high-latitude location. This GISTM
receiver is able to measure the Total Electron Content (TEC),
and both the amplitude and phase scintillations. This study
focuses on the phase scintillation observed over Alert for 26-
month period from June 2008 until July 2010 where it was mostly
during the minimum state of solar activity. It is found that at
least 93% of the phase scintillations, σφ of the observed data were
in the range of 0-0.1 rad. The remaining 7% varied from 0.1 to
0.7 rad, where it mostly never exceeded 0.2 rad. σφ < 0.15 is
considered as insignificant. Phase scintillations were found to be
increased with the increasing of solar activity where most of the
cases of σφ > 0.15 rad were detected in 2010. |
