Trans - ionospheric GPS signal delay gradients observed over mid - latitude Europe during the geomagnetic storms of October - November 2003
Ionospheric disturbances are known to have adverse effects on the satellite-based communication and navigation. One particular type of ionospheric effects, observed during major geomagnetic storms and threatening the integrity performance of both ground-based and space-based GNSS augmentation systems, is the sharp increase/decrease in the ionospheric delay that propagates in horizontal directio...
متن کاملIonospheric redistribution during geomagnetic storms
[1]The abundance of plasma in the daytime ionosphere is often seen to grow greatly during geomagnetic storms. Recent reports suggest that the magnitude of the plasma density enhancement depends on the UT of storm onset. This possibility is investigated over a 7year period using global maps of ionospheric total electron content (TEC) produced at the Jet Propulsion Laboratory. The analysis confir...
متن کاملResponses of equatorial anomaly to the October − November 2003
The responses of Equatorial Ionization Anomaly (EIA) to the superstorms of October−November 2003 were investigated using the total electron content (TEC) measured with global positioning system (GPS) receivers in China, Southeast Asia, Australian (CSAA), and the American regions. Enhanced EIA was seen to be correlated with the southward turning of the interplanetary magnetic field Bz. In both t...
متن کاملSuperposed epoch analysis of a whistler instability criterion at geosynchronous orbit during geomagnetic storms
accelerating relativistic outer-belt electrons in the aftermath of geomagnetic storms. Using measurements from the Los Alamos Magnetospheric Plasma Analyzers in geosynchronous orbit, we perform a superposed-epoch study of the storm-time behavior of the inferred plasma-sheet whistler growth parameter. Separate analyses are done for storms that result in strong relativistic electron enhancements ...
متن کاملVoyager 2 observations related to the October – November 2003 solar events
[1] A transient flow system observed at 1 AU from October 24–November 7, 2003 (consisting of several shocks, ejecta and possibly other flows) moved away from the Sun for 180 days to 73 AU, where Voyager 2 (V2) observed a large Merged Interaction Region (MIR) associated with a fast (560 km/s) stream that followed a forward shock and moved past V2 for 1.5 solar rotations. The MIR and stream were ...
