Observations of the ionospheric response to the 15 December 2006 geomagnetic storm: Long-duration positive storm effect

[1] The long-duration positive ionospheric storm effect that occurred on 15 December 2006 is investigated using a combination of ground-based Global Positioning System (GPS) total electron content (TEC), TOPEX and Jason-1 TEC, and topside ionosphere/ plasmasphere TEC, GPS radio occultation, and tiny ionospheric photometer (TIP) observations from the Constellation Observing System for Meteorolog...

Sounding of the topside ionosphere/plasmasphere based on GPS measurements from CHAMP: Initial results

[1] Beside the GPS radio occultation measurements of the troposphere and ionosphere, the CHAMP satellite tracks presently up to 8 GPS satellites simultaneously for navigation. The received dual frequency GPS signals provide valuable information on the ionization state of the topside ionosphere and plasmasphere. This paper briefly describes a new developed model assisted technique to improve the...

Plasmasphere and Upper Ionosphere Contributions and Corrections During the Assimilation of GPS Slant TEC

RIMT: A tool for Regional Ionospheric Mapping and Tomography using GPS data

The ionosphere is about 60-1000 km above the earth’s surface, which is actually plasma of ionized gas of the upper atmosphere by solar radiation and high-energy particles from the Sun. The ionized electrons concentrations change with height above earth’s surface, location, time of the day, season, and amount of solar activity. The total electron content (TEC) and electron density profiles are t...
