A Case-Study: Correlation of GNSS Distortions and the Aurora During Increasing Solar Activitity — •Michael Danielides1, Mike Rietveld2, Mike Kosch3, Andrew Senior3, and Norbert Jakowski11DLR Institut für Kommunikation und Navigation, 17235 Neustrelitz, Germany — 2EISCAT Scientific Association, Tromsö, Norway — 3Lancaster University, Lancaster, UK

Space weather impacts at high latitudes are often related to particle precipitation as displayed by the Aurora. It is known that trans-ionospheric radio signals utilized by Global Navigation Satellites Systems (GNSS) are disturbed by these space weather impacts. The total electron content (TEC), derived from GNSS signal measurements along the ray path between satellite and ground receiver, is used to identify localized ionospheric disturbances. TEC is then correlated with simultaneously detected aurora structures. The EISCAT UHF radar is used to record ionospheric electron density and temperature height distributions along the magnetic field-line and along the GNSS line of sight.

The present case study reports on a multi-instrumental measurement campaign consisting of GNSS signal measurements, all-sky optical observations and EISCAT UHF radar measurements at quiet and disturbed geomagnetic conditions during increasing solar activity and discusses related ionospheric phenomena.
