Short summary
This study investigates an ionospheric anomaly in Antarctica that affects electron concentration during summer. We analyse data from four stations, revealing different trends depending on the season and time of day. Vernadsky shows strong influence of the anomaly, while Port Stanley is less affected, and other stations do not show a clear pattern. These results highlight how local phenomena can modify global trends, providing new information about the Earth's space environment.

Short summary
The International Reference Ionosphere (IRI) is a widely used ionospheric empirical model based on observations from a worldwide network of ionospheric stations. It is reasonable, then, to expect that it captures long-term changes in ionospheric parameters linked to trend forcings like greenhouse gases increasing concentration and the Earth's magnetic field secular variation. We show that the IRI model can be a valuable tool for obtaining preliminary approximations of experimental trends.

Short summary
This study explores how solar sunspot number (Sn) compares with other solar indicators like solar radio fluxes in predicting changes in Earth's ionosphere, particularly its critical frequency, over more than 60 years. The work finds that Sn, despite recent fluctuations in other proxies, remains the most stable predictor across all time periods. When adjusting for potential data saturation, Sn outperforms other proxies, providing a more accurate forecast of long-term ionospheric trends.

Short summary
Our research investigates how different proxies of solar activity influence long-term trends in the Earth's ionosphere. By analyzing data from two mid-latitude stations up to 2022, we found that the choice of solar activity measures significantly affects trends in ionospheric electron density, while trends in ionospheric height remain more stable. Selecting the correct solar activity measure is crucial for accurate density trend predictions and improving space weather forecasting models.
