Climatology of GNSS ionospheric scintillation at high latitudes

We analyse GNSS ionospheric scintillation data in the polar areas of both hemispheres to develop a climatology over a large geomagnetic quiet period. The conditions of the near-Earth environment leading to scintillation scenarios are investigated via scintillation occurrence. Within this scope we re...

Description
Summary:We analyse GNSS ionospheric scintillation data in the polar areas of both hemispheres to develop a climatology over a large geomagnetic quiet period. The conditions of the near-Earth environment leading to scintillation scenarios are investigated via scintillation occurrence. Within this scope we realize maps of scintillation occurrence as a function of the magnetic local time(MLT) and of the altitude adjusted corrected geomagnetic coordinates (AACGM). The maps are realized merging observations from a network of four GISTM (GPS Ionospheric Scintillation and TEC Monitor) in the Northern Europe and two GISTM in Antarctica during the year 2008. The results highlight the possibility to investigate the impact of ionospheric irregularities on the phase and amplitude of GNSS signals, evidencing the auroral and cusp/cap contributions. This works aims to contribute to development of nowcasting and forecasting tools for GNSS ionospheric scintillation. Published Università di Padova 3.9.
