Dependence of long-term trends in foF2 at middle latitudes on different solar activity proxies
J Laštovička - Advances in Space Research, 2024 - Elsevier
The most studied ionospheric parameter for long-term trends is foF2. The dominant factor of
foF2 variability is the solar cycle, which is much stronger than the long-term trends …

The effect of mixing EUV proxies on the correlation with foF2 and on long-term trends estimations
Solar proxies are a valuable tool used in most atmospheric models to simulate or predict the
state and variation of the different layers linked to the solar source. In this work, we analyze …
