| Zusammenfassung |
| We analyze data of ionospheric scintillation in the geographic latitudinal
range 44°–88° N during the period of October, November and December
2003 as a first step to develop a "scintillation climatology" over
Northern Europe. The behavior of the scintillation occurrence as a function
of the magnetic local time and of the corrected magnetic latitude is
investigated to characterize the external conditions leading to
scintillation scenarios. The results shown herein, obtained merging
observations from four GISTM (GPS Ionospheric Scintillation and TEC
Monitor), highlight also the possibility to investigate the dynamics of
irregularities causing scintillation by combining the information coming
from a wide range of latitudes. Our findings associate the occurrences of
the ionospheric irregularities with the expected position of the auroral
oval and ionospheric troughs and show similarities with the distribution in
magnetic local time of the polar cap patches. The results show also the
effect of ionospheric disturbances on the phase and the amplitude of the GPS
signals, evidencing the different contributions of the auroral and the
cusp/cap ionosphere. |
