Global electron content: a new conception to track solar activity
TL;DR: In this paper, the authors developed a method and programs for estima- tion of the global electron content (GEC) from GPS measure- ments, using the ionosphere models IRI-2001 and NeQuick.

GIM-TEC adaptive ionospheric weather assessment and forecast system
TL;DR: IWAF as mentioned in this paper is a computer software package designed to assess and predict the world-wide representation of 3-D electron density profiles from the Global Ionospheric Maps of Total Electron Content (GIM-TEC).
Journal ArticleDOI
Topside ionospheric scale height analysis and modelling based on radio occultation measurements
TL;DR: In this article, a new method of retrieving the top-side ionospheric scale height based on radio occultation observations onboard low-earth-orbiting satellites is presented. But the knowledge of the scale height in the ionosphere region remains rather poor due to the insufficient observations carried so far.

Ionospheric anomalies detected by ground-based GPS before the Mw7.9 Wenchuan earthquake of May 12, 2008, China
TL;DR: In this paper, the vertical total electron content (VTEC) derived from ground-based GPS observations was examined to examine the ionospheric variations during the Mw7.9 Wenchuan earthquake which Occurred on May 12, 2008, in China.

Estimation of the transmitter and receiver differential biases and the ionospheric total electron content from Global Positioning System observations
TL;DR: In this paper, a method based on a Kalman filtering approach was proposed to estimate the biases in the GPS satellites and receivers and the total electron content at each GPS station using dual GPS data.

Global positioning system phase fluctuations at auroral latitudes
TL;DR: In this paper, the authors used observations of a diversity of propagation paths of Global Positioning System satellites from each of 11 high-latitude stations to determine the behavior pattern for the development of phase fluctuations in the auroral and subauroral irregularity regions.

Ionospheric storm effects at subauroral latitudes: A case study
TL;DR: In this paper, an attempt is made to classify ionospheric storm effects at subauroral latitudes according to their presumed origin, using ionosonde, electron content, and DE 2 satellite data.

Total electron content of the ionosphere during thegeomagnetic storm on 10 January 1997
TL;DR: In this paper, the total electron content (TEC) of the ionosphere over Europe and over three North American stations for the 6-11 January 1997 storm event was derived.

Relationships between GPS-signal propagation errors and EISCAT observations
TL;DR: In this article, the authors estimate the total electron content (TEC) along the ray path between satellite and receiver using about ten Euro- pean GPS receiving stations of the International GPS Service for Geodynamics (IGS), the TEC over Europe is estimated within the geographic ranges.
