The ESA Swarm mission to help ionospheric modeling: a new NeQuick topside formulation for mid-latitude regions.

ABSTRACT: The ionospheric topside representation made by the NeQuick model is improved by correcting the H₀ parameter used by the model to calculate the topside scale height. The task is accomplished by fitting the NeQuick topside analytical function through two anchor points: the F2-layer absolute electron density maximum; the electron density value as measured by Swarm satellites from December 2013 to September 2018. Specifically, two-dimensional grids of H₀ as a function of foF2 and hmF2 are obtained, one by employing data from Swarm A and Swarm C, both flying at about 460 km of altitude, and the other one by employing data from Swarm B, flying at about 520 km of altitude. These two grids are used to calculate corrected values of H₀, which allows a more reliable d
