Equatorial total electron content (TEC) at low and high solar activity
Advances in Space Research, 2009Abstract Total electron content (TEC) derived from ionosonde data recorded at the station of Korhogo (Lat = 9.33°N, Long = 5.43°W, Dip = 0.67°S) are compared to the International Reference Ionosphere (IRI) model predicted TEC for high (1999) and low (1994) solar activity conditions.

Are trends in total electron content (TEC) really positive?
Journal of Geophysical Research: Space Physics, 2013The total electron content (TEC) is a primary ionospheric parameter as it can be studied globally using signals of GNSS satellites. Lean et al. (2011, JGR) in the first study of long‐term trends in TEC found positive trends for the period 1995–2010 based on TEC derived from global GPS observations.

On the sensitivity of total electron content (TEC) to upper atmospheric/ionospheric parameters
Journal of Atmospheric and Solar-Terrestrial Physics, 2005Abstract The total electron content (TEC) is a key ionospheric parameter for various space weather applications. Over the last decade an extensive database of TEC measurements has become available from both space- and ground-based observations, and these measurements have established the general morphology of the global TEC distributions.

Construction of LSTM model for total electron content (TEC) prediction in Thailand
2021 18th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2021Total electron content (TEC) is an important parameter often used to explain the ionosphere characteristics and disturbances. Severe local disturbance often originates in the equatorial region then expand to low- and mid-latitude regions. Vertical TEC (VTEC as well as slant TEC (STEC) modeling’s and predictions attract attention from researchers ...

Bidirectional LSTM for ionospheric vertical Total Electron Content (TEC) forecasting
2017 IEEE Visual Communications and Image Processing (VCIP), 2017The ionosphere is a region over earth's atmosphere which is ionized by solar radiation. It plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere, furthermore, it has practical importance for its effects on radio propagation to earth.

Improving Total Electron Content (TEC) Models for Geodetic Applications
2020<p>Increasing the quality of ionosphere modeling is crucial and remains a challenge for many geodetic applications such as GNSS Precise Point Positioning (PPP) and navigation. Ionosphere models are the main tool to provide an estimation of Total Electron Content (TEC) to be corrected from GNSS career phase and pseudorange ...

GPS Total Electron Content (TEC) estimation using single station measurements
2019 Sixth International Conference on Aerospace Science and Engineering (ICASE), 2019Global Positioning System (GPS) operates in the microwave band, for which ionosphere is a dispersive medium and has a frequency-dependent effect on the signals. This effect can be used to gather vital information about the ionosphere itself in terms of the Vertical Total Electron Content (vTEC).
