Atmospheric and Space Physics / Physique atmosphérique et de l'espace (DASP-DPAE)

Invited Speaker / Conférencier(ère) invité(e)

This presentation will discuss Hydro-Quebec’s historical records and observations of geomagnetic disturbance. We will show how data/forecasts are used and integrated in control room operation. A real event will be presented in detail. Looking at the future, we will illustrate some gaps and research needs. The main idea of the presentation is that electricity provides relevant feedbacks to...

Bursts of enhanced electron density in the ionospheric D-region due to photoionization by X-ray radiation from solar X-ray flares leads to a fadeout of short wave signals, potentially causing a loss of high frequency radio communication in affected regions. D-region absorption is typically monitored using riometer instruments which typically operate at 30 MHz. There are well established...

1966. Exploring the use of the Empirical Canadian High Arctic Ionospheric Model (E-CHAIM) and other empirical ionospheric electron density models at high latitudes (I)

Invited Speaker / Conférencier(ère) invité(e)

In this study, we begin by presenting an overview of the methodology behind existing empirical ionospheric electron density models, including the E-CHAIM and International Reference Ionosphere (IRI). Several limitations have been identified in the methodology used to parameterize the IRI (Themens et al., 2014, 2016, and 2017a), particularly in its application at high latitudes. Using these...
