versatile incoherent scatter (IS) radar facilities on the mainland of northern Scandinavia (the …

This paper presents a review on the PECASUS service, which provides advisories on
enhanced space weather activity for civil aviation. The advisories are tailored according to …

The 2015 St. Patrick's day storm was the first storm of solar cycle 24 to reach a level of
“Severe” on the NOAA geomagnetic storm scale. The Norwegian Map** Authority is …

This paper presents research on polar cap ionosphere space weather phenomena
conducted during the European Cooperation in Science and Technology (COST) action …

The correlation between the rate of TEC index (ROTI) and scintillation indices S 4 and σ Φ
for low-latitude region is analyzed in this study, using data collected from a Global …

The polar ionosphere is often characterized by irregularities and fluctuations in the plasma
density. We present a statistical study of ionospheric plasma irregularities based on the …

We directly compare the relative GPS scintillation levels associated with regions of
enhanced plasma irregularities called auroral arcs, polar cap patches, and auroral blobs …

In early September 2017, several space weather events triggered disturbed conditions of the
near‐Earth space. The combination of two coronal mass ejection arrivals, associated with an …

High-rate sampling data of Global Navigation Satellite Systems ionospheric scintillation
acquired by a network of GPS Ionospheric Scintillation and TEC Monitor receivers located in …

As societal dependence on transionospheric radio signals grows, space weather impact on
these signals becomes increasingly important yet our understanding of the effects remains …
