|Abstract: ||The paper describes results of the studies devoted to the solar activity impact on the Earth’s upper atmosphere and ionosphere,
conducted within the frame of COST ES0803 Action.
Aim: The aim of the paper is to represent results coming from different research groups in a uniﬁed form, aligning their speciﬁc topics into the general context of the subject.
Methods: The methods used in the paper are based on data-driven analysis. Speciﬁc databases are used for spectrum analysis,
empirical modeling, electron density proﬁle reconstruction, and forecasting techniques.
Results: Results are grouped in three sections: Medium- and long-term ionospheric response to the changes in solar and geomag-
netic activity, storm-time ionospheric response to the solar and geomagnetic forcing, and modeling and forecasting techniques.
Section 1 contains ﬁve subsections with results on 27-day response of low-latitude ionosphere to solar extreme-ultraviolet (EUV)
radiation, response to the recurrent geomagnetic storms, long-term trends in the upper atmosphere, latitudinal dependence of total electron content on EUV changes, and statistical analysis of ionospheric behavior during prolonged period of solar activity.
Section 2 contains a study of ionospheric variations induced by recurrent CIR-driven storm, a case-study of polar cap absorption
due to an intense CME, and a statistical study of geographic distribution of so-called E-layer dominated ionosphere.
Section 3 comprises empirical models for describing and forecasting TEC, the F-layer critical frequency foF2, and the height of
maximum plasma density. A study evaluates the usefulness of effective sunspot number in specifying the ionosphere state. An
original method is presented, which retrieves the basic thermospheric parameters from ionospheric sounding data.|
