This article investigates the impact of big data on the actuarial sector. The growing fields of
applications of data analytics and data mining raise the ability for insurance companies to …

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 …

On November 1st and 2nd, 2021, four Halo coronal mass ejections were ejected from the
Sun, releasing billions of tons of high-energy particles into interplanetary space. These were …

This paper aims to provide an overview on recent advances in ionospheric modeling
capabilities, with the emphasis in the efforts relevant to electron density variability. The …

From 7 to 10 March 2012 a series of magnetospheric disturbances caused perturbations in
the ionospheric electron density. Analyzing the interplanetary causes in each phase of this …

Abstract Recent Solar Cycle 24 is characterized by the occurrence of three strong
disturbances near an equinox. In this contribution, the responses of the ionosphere to the …

Electron density measured at high latitudes by the Swarm satellites was compared with
measurements by the incoherent scatter radars at Resolute Bay and Poker Flat. Overall, the …

Electron density measured at high latitudes by the Swarm satellites is compared with the
measurements by the RISR incoherent scatter radars as the satellites fly by the radars' field …

This study correlates different ionospheric parameters with the integrated solar extreme
ultraviolet radiation (EUV) radiation to analyze the delayed ionospheric response, testing …

Abstract Since 1988 the Upper Atmosphere Physics unit of the Istituto Nazionale di Geofisica
e Vulcanologia (INGV) has provided maps of Maximum Usable Frequency (MUF) and skip …
