Hence, even in this highly

Long - term trends in the upper atmosphere - ionosphere are a
complex problem due to simultaneous presence
of several drivers
of trends, which behave in a different way: increasing atmospheric concentration
of greenhouse gases, mainly CO2, long - term changes
of geomagnetic and solar
activity, secular change
of the Earth's main magnetic
field, remarkable long - term changes
of stratospheric ozone concentration, and very probably long - term changes
of atmospheric dynamics, particularly
of atmospheric wave
activity (Lastovicka 2009; Qian et al. 2011; Lastovicka et al. 2012).
