Earth magnetic field and geomagnetic activity effects on long-term trends in the F2 layer at mid-high latitudes
It is well known that the Earth magnetic field, as well as geomagnetic activity, presents long-term variations.Both phenomena affect the height of the F2 layer peak, hmF2, and the maximum electron concentration estimated by foF2. Experimental data of three mid-high latitude stations (Argentine Islan...
