| Zusammenfassung |
| This paper deals with two problems, methods of foF2 trend
determination and origin of trends in foF2, both being controversial in
current literature. We found that various regression-based methods and
artificial neural network-based method of Yue et al. (2006) provided
comparable results within uncertainties caused mainly by various ways of
removing/suppressing the dominant solar cycle effect. The role of
geomagnetic activity in the observed trends in foF2 was probably substantial
and might be still even rather dominant in the last quarter of the 20th
century. |
