TL;DR: NeQuick as discussed by the authors is a three-dimensional and time dependent ionospheric density model developed at the Aeronomy and Radiopropagation Laboratory of the Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste, Italy and at the Institute for Geophysics, Astrophysics and Meteorology of the University of Graz, Austria.

TL;DR: In this paper, the authors compare ISIS-2 topology profiles with IRI and NeQuick topology models and identify weak points in their topology formulation, and present an alternative formulation based on k values derived from experimental profiles.

TL;DR: In this article, three different models of three dimensional electron density distributions in the ionosphere have been constructed for global as well as regional use, which allow the use of global or regional maps for foF2 and M(3000)F2.

TL;DR: In this paper, the effects of the St Patrick's Day storm of 2015, with its ionospheric response at middle and low latitudes, were analyzed using global and regional electron content, and the results showed that the American region exhibits the most remarkable increase in vertical total electron content (vTEC), while in the Asian sector, the largest decrease in vTEC is observed.

TL;DR: In this article, the NeQuick ionosphere electron density model was adapted to GPS-derived Total Electron Content (TEC) data and ionosonde measured peak parameters values.
