Regional Ionospheric Trend Statistics: Ionolab-Pdf
(Tubitak Scientific & Technical Research Council Turkey, 2017)The ionosphere plays an important role for HF bands, space-based positioning systems, satellite communication, and propagation. The variability of the ionosphere has a complex spatiotemporal characteristic, which depends ... -
Regional Model-Based Computerized Ionospheric Tomography Using Gps Measurements: Ionolab-Cit
(Amer Geophysical Union, 2015)Three-dimensional imaging of the electron density distribution in the ionosphere is a crucial task for investigating the ionospheric effects. Dual-frequency Global Positioning System (GPS) satellite signals can be used to ... -
Regional Tec Mapping with Random Field Priors and Kriging
(Amer Geophysical Union, 2008)Total Electron Content ( TEC) is an important parameter in monitoring ionospheric variability. In a given region, TEC can be obtained only by interpolation of measurements due to sparsity of the useful data. The lack of a ... -
Regularized Estimation of Tec from Gps Data for Certain Midlatitude Stations and Comparison with the Iri Model
