| Session Description | The total electron content (TEC) observations measured by the worldwide network of ground-based GNSS receivers have greatly enhanced our understanding on the ionosphere. Recently, low earth orbit (LEO) satellites equipped with GNSS receivers for both precise orbit determination and radio occultation (RO) observations provide an important way of measuring TEC or electron density profiles with good spatio-temporal resolutions. GNSS ionospheric observations have shown valuable applications in revealing the underlying physical mechanisms of the variation of the ionosphere. We are organizing this session for the purposes of promoting theory, algorithm development and novel applications related to GNSS TEC and electron density retrievals and presenting recent achievements in understanding the ionosphere variability using GNSS data. Topic areas of particular interest to this session include, but not limited to: 1) Retrieval methods of GNSS TEC using both ground-based (CORS national positioning infrastructure) or space-based (RO) receivers, such as ambiguity resolution, mapping function technique, differential code biases estimation, algorithm optimization, performance and quality analysis; 2) GNSS ionospheric tomography and ionospheric data assimilation techniques; 3) Development and application of modernized GNSS signals (L2C, L5) and new GNSS constellations (e.g., BeiDou, GALILEO) in space weather monitoring; 4) Applications of GNSS observations in studying the ionosphere, particularly for the topside ionosphere; 5) Characterization of ionospheric scintillation and irregularities and their influences on GNSS signals. |
