Variations of total electron content during geomagnetic disturbances: A nlodel/olmervation comparison
This paper studies the ionospheric response to a major geomagnetic storm of October 18-19, 1995, using the thermosphere-ionosphere electrodynamics general circulation model (TIEGCM) simulations and the global ionospheric maps (GIM) of total electron content (TEC) observations from the Global Positioning System (GPS) worldwide network. The TIE-GCM results, which utilize the realistic time-depend...
متن کاملEffects of St Patrick’s Day Intervals Geomagnetic Storms on the Accuracy of GNSS Positioning and Total Electron Content over Nigeria
Total electron content (TEC) and GNSS positioning error over two Nigeria GNSS stations (CLBR: Latitude; 4.9503°E, Longitude; 8.3514°N, FUTY: Latitude; 9.3497°E, Longitude; 12.4978°N) were studied during the geomagnetic storms of March 17, 2015 minimum Dst (Disturbed storm time) -223nT and that of March 17, 2013 minimum Dst of -132nT (the St. Patrick’s...
متن کاملSolar flare signatures of the ionospheric GPS total electron content
6 [1] In this study, ionospheric solar flare effects on the total electron content (TEC) and 7 associated time rate of change (rTEC) derived from ground-based global positioning 8 system (GPS) receivers in the midday region are examined. The occurrence times and 9 locations of 11 solar flares are isolated from the 1–8 Å X-ray radiations of the 10 geosynchronous operational environmental satelli...
متن کاملTotal Ionospheric Electron Content Calibration Using SERIES GPS Satellite Data
This article describes the current status of the Deep Space Network advanced systems research into ionospheric calibration techniques, based on Global Positioning System (GPS) data. A GPS-based calibration system is planned to replace the currently used Faraday rotation method by 1989. The SERIES receiver system used in this research determines the differential group delay of signals transmitte...
متن کاملFeatures of annual and semiannual variations derived from the global ionospheric maps of total electron content
In the present work we use the NASA-JPL global ionospheric maps of total electron content (TEC), firstly to construct TEC maps (TEC vs. magnetic local time MLT, and magnetic latitude MLAT) in the interval from 1999 to 2005. These TEC maps were, in turn, used to estimate the annualto-mean amplitude ratio, A1, and the semiannual-to-mean amplitude ratio, A2, as well as the latitudinal symmetrical ...
