“…The auroral and radiation belt electron precipitations occur in connection with magnetospheric disturbances and reach maxima during the decay phase of the solar cycle. The magnetospheric-auroral electrons are absorbed in the upper atmosphere, but the bremsstrahlung produced by these electrons can penetrate down to 20 km [3,4,6].…”

The review generalizes experimental data on the relationships between the solar activity agents (space weather) and atmosphere constituents. It is shown that high-energy solar protons (SPE) make a powerful impact on photo-chemical processes in the polar areas and, correspondingly, on atmospheric circulation and planetary cloudiness. Variations of the solar UV irradiance modulate the descent rate of the zonal wind in the equatorial stratosphere in the course of quasi-biennial oscillation (QBO), and thus control the total duration (period) of the QBO cycle and, correspondingly, the seasonal ozone depletion in the Antarctic. The geo-effective solar wind impacts on the atmospheric wind system in the entire Southern Polar region, and influences the dynamics of the Southern Oscillation (ENSO).

“…EPP mostly contains electrons and protons and depends on the energy and intensity of the precipitating flux. EPP leads to increased atmospheric ionization rates [21][22][23][24][25][26][27]. Solar energetic protons precipitate mostly into the middle mesosphere and down to the stratosphere, electrons affect the lower thermosphere to the upper mesosphere.…”

Here we provide a selection of extreme geomagnetic storms of the last century based on NOAA classification which lead to the energetic particle precipitation (EPP). EPP of such geomagnetic storms can cause power outages, communication failures, and navigation problems as well as impact on the environment and the ozone level. Studies of historical extreme geomagnetic storms together with EPP for large space weather events in the space era can help to reconstruct the parameters of extreme events of past centuries.

Energetic particle precipitation induces ionization of the atmosphere which initiates a chain of reaction cycles affecting atmospheric composition and dynamics potentially down to surface weather systems. Ionization rates are retrieved based on yield functions or pre-calculated monoenergetic electron flux and energy spectra of precipitated energetic particles. Usually, information about energy spectra is obtained from satellites, balloons, and various ground-based observations. In all cases, some assumptions about spectral distribution for the entire energy range have to be made. As ionization rates are widely used in chemistry-climate models to estimate the atmospheric response to particle forcing, evaluation of the energy spectra is a key task in the solar-terrestrial studies. In this paper, it is shown that possible uncertainties of the ionization rates retrieval based on different spectral functions can lead to large disagreements in the ionization rates, with implications for the modelled response of atmospheric composition and dynamics to electron precipitation.
