The ionospheric equivalent slab thickness (τ) is a parameter characterizing both the
distribution of the plasma in the ionosphere and the shape of the corresponding vertical …

This paper is a final review of the Simplified Ionospheric Regional Model (SIRM) developed
as a prototype in the early 1990s and improved in the following years. By means of an …

In the paper we study the ionosphere response to the March 2015 severe geomagnetic
storm according to Eurasian high-middle latitude ionosonde chain. On the basis of the …

This paper presents how the magnetosphere–plasmasphere–ionosphere system was
affected as a whole during the geomagnetic storm peaking on 27 May 2017. The …

The ionospheric topside representation made by the NeQuick model is improved by
correcting the H 0 parameter used by the model to calculate the topside scale height. The …

Ionosondes have remained the main provider of continuous “ground-truth” observations of
the subpeak ionospheric plasma density, available for assimilation in weather models with …

In this work, we evaluate the SUPIM-INPE model prediction of the 14 December 2020, total
solar eclipse over the South American continent. We compare the predictions with data from …

This paper presents a comparison between standard ionospheric parameters manually and
automatically scaled from ionograms recorded at the high-latitude Sodankylä Geophysical …

An empirical method to model the lower part of the ionospheric topside region from the F 2
layer peak height to about 500–600 km of altitude over the European region is proposed …

The purpose of this work is to present a new computational tool for ionogram generated with
a Canadian Advanced Digital Ionosonde (CADI). This new tool uses the fuzzy relation …
