G. Hubert, S. Aubry. (2021). Study of the Impact of Past Extreme Solar Events on the Modern Air Traffic (Vol. 19).
Abstract: The ancient solar energetic particle (SEP) events of 774/775 CE and 993/994 CE were characterized thanks to radionuclide productions stored in environmental archives as ice cores or tree rings. Primary cosmic ray spectra deduced from these cosmogenic isotope data indicate that the impact of these extreme SEP events would have been much more significant than any of the ones observed during the modern era. However, the impact of these should be studied more accurately in the framework of the ambient dose equivalent impacting aircrew and passengers in the air traffic context by considering physical parameters such as time profile or anisotropy properties. In this study, the impact that 774/775 CE and 993/994 CE past extreme SEP events could have had on modern air traffic is discussed. Possible event spectra for these ancient events are derived from the spectra ground-level enhancement (GLE) 5 and GLE 69, which have been observed during the modern era and have been widely studied/characterized using measurements. The investigations include the impact of the SEP activity on ambient dose equivalent, including detailed analyses considering route, airplane characteristics (departure, arrival, continent, airplane type), and the time occurrence of the SEP event. Statistical analyses show that additional dose levels can reach values on the order of 70 mSv, which is absolutely significant considering the current air traffic recommendations. The orders of magnitude of the ambient dose equivalent induced during past extreme SEP events raises a number of issues, both for aircrews and for avionics hardware. This study demonstrates that simulations can be useful for the evaluation of risks in case of extreme SEP events.

Belehaki, I. Stanislawska, J. Lilensten. (2009). An Overview of Ionosphere – Thermosphere Models Available for Space Weather Purposes.
Abstract: Our objective is to review recent advances in ionospheric and thermospheric modeling that
aim at supporting space weather services. The emphasis is placed on achievements of European
research groups involved in the COST Action 724. Ionospheric and thermospheric modeling on time
scales ranging from a few minutes to several days is fundamental for predicting space weather effects
on the Earth's ionosphere and thermosphere. Space weather affects telecommunications, navigation
and positioning systems, radars, and technology in space. We start with an overview of the physical
effects of space weather on the upper atmosphere and on systems operating at this regime. Recent
research on drivers and development of proxies applied to support space weather modeling efforts are
presented, with emphasis on solar radiation indices, solar wind drivers and ionospheric indices. The
models are discussed in groups corresponding to the physical effects they are dealing with, i.e.
bottomside ionospheric effects, trans-ionospheric effects, neutral density and scale height variations,
and spectacular space weather effects such as auroral emissions. Another group of models dealing with
global circulation are presented here to demonstrate 3D modeling of the space environment. Where
possible we present results concerning comparison of the models' performance belonging to the same
group. Finally we give an overview of European systems providing products for the specification and
forecasting of space weather effects on the upper atmosphere, which have implemented operational
versions of several ionospheric and thermospheric models.

Abstract: This paper summarizes recent advances in our understanding of geomagnetism, and its relevance to terrestrial space weather. It also discusses specific core magnetic field features such as the dipole moment decay, the evolution of the South Atlantic anomaly, and the location of the magnetic poles that are of importance for the practice of space weather.
