The more frequent ejections of high-energy electromagnetic radiation and particles from the sun around the time of the solar maximum results in greater ionospheric electron densities and more variable densities. And as the signals from the gps satellites must pass through this more active ionosphere on their way to earth-.
Sudden stratospheric warming impacts on the ionosphere-thermosphere system – a review of recent progress.
Over the past several years significant advances have been made in all areas of ionospheric modelling and mapping studies. Ionospheric models and maps of varying complexity have been formulated from analytic and simple numerical models that are user friendly calculations to complete general circulation models that require hours on todays supercomputers.

Iri is recognized as the official standard for the ionosphere by the international standardization organization (iso), the international union of radio science ( ursi).
Its original purpose was to analyze the ionosphere and investigate the potential for developing.
Radial basis function (rbf) interpolation with multi-quadric is developed to perform ionospheric total electron content (tec) mapping for the chinese region between 15°n ~ 40°n and 100°e ~ 125°e.
Abstract global ionospheric mapping (gim) is a new and emerging technique for determining global ionospheric tec (total electron content) based on measurements from a worldwide network of global positioning system (gps) receivers.
Ionospheric mapping, traditionally based on station data suffers from the inadequateness of the network of stations, particularly in the equatorial and the polar zones, and from involved structures in certain geographical regions, as in the equatorial belt and, in particular the polar caps.
Ionospheric mapping, traditionally based on station data suffers from the inadequateness of the network of stations, particularly in the equatorial and the polar zones, and from involved structures in certain geographical regions, as in the equatorial belt and, in particular the polar caps. Distinct aeronomic conditions require additional information and separate mapping.
Hence these forecast models, including the prism used by the airforce, are usually empirical, rather than the first-principles models. In addition, until recently ionospheric research suffered from lack and sparsity of observational data. This situation is changing dramatically owing mostly to advances in remotesensing of the ionosphere from space.

The ionospheric sporadic e-layer (es) is an irregular layer of ionisation occuring within the ionospheric e-layer and characterised by small thin “clouds” of intense ionisation, an altitude-thin layer at an unpredictable altitude and/or an unexpected intensity. Sporadic-e events may last from just a few minutes up to several hours.

Icls setting for global ionospheric mapping with spherical harmonic functions spherical harmonic functions have been used by two igs iaacs, namely, code and esa, to represent global ionospheric delays for gnss (schaer, 1999).
Iri model for mapping ionospheric electron density at the certain heights over european region, as at hmf2 and at fixed f1-region heights, during quiet ionospheric conditions. Dur-ing disturbed conditions iri still cannot produce appropriate values mainly at f1 heights and therefore reasonably accu-rate n(h) profile as a whole.
