Jones R. M., L. A. Ostrovsky and A. J. Bedard (June 2017): Ionospheric effects of magneto - acoustic - gravity waves: Dispersion relation.

Future developments may include a more sophisticated method for its derivation in order to anticipate localized ionospheric effects and the quantitative description of its relation to the intensity of ionospheric activity.

This Project aims to determine through numerical simulation the effects which spacecraft launched in Norway have on the peripheral ionospheric plasma environment in the observed region.

Thus, solar activity itself has little or no direct effect on observed ionospheric trends.

Limitations are imposed for small - scale effects, such as positive effects of short duration observed locally indicating ΔR12eff responses to the averaged ionospheric activity over Europe.

This is achieved through the cooperation of an autoregression forecasting algorithm, called Time Series AutoRegressive — TSAR (Koutroumbas et al. 2008), with the empirical Storm Time Ionospheric Model — STIM (Tsagouri & Belehaki 2006, 2008) that formulates the ionospheric storm - time response based on solar wind input, exploiting recent advances in ionospheric storm dynamics that correlate the ionospheric storm effects with solar wind parameters (e.g., the magnitude of the IMF and its rate of change as well as the IMF's orientation in the north - south Ionospheric Model — STIM (Tsagouri & Belehaki 2006, 2008) that formulates the ionospheric storm - time response based on solar wind input, exploiting recent advances in ionospheric storm dynamics that correlate the ionospheric storm effects with solar wind parameters (e.g., the magnitude of the IMF and its rate of change as well as the IMF's orientation in the north - south ionospheric storm - time response based on solar wind input, exploiting recent advances in ionospheric storm dynamics that correlate the ionospheric storm effects with solar wind parameters (e.g., the magnitude of the IMF and its rate of change as well as the IMF's orientation in the north - south ionospheric storm dynamics that correlate the ionospheric storm effects with solar wind parameters (e.g., the magnitude of the IMF and its rate of change as well as the IMF's orientation in the north - south ionospheric storm effects with solar wind parameters (e.g., the magnitude of the IMF and its rate of change as well as the IMF's orientation in the north - south direction).

The analysis of the effects of these magnetic disturbances, occurring within the period 2006 — 2009 on ionospheric F2 - layer, showed significant departure of the main peak parameters from the corresponding 27 - days running means.

To evaluate the effects of geomagnetic disturbances on the ionospheric F2 - layer, we used hourly measurements of foF2 and hmF2 and their 27 - days running means centered on the culmination (minimum Dst) day of each analyzed geomagnetic disturbance.

In particular, ionospheric disturbances caused by large - scale phenomena such as the prolonged negative and positive effects observed all over Europe are sufficiently captured in ΔR12eff variation from the onset of the disturbance until the full recovery (Fig. 16).
