FoF2 long-term trend linked to Earth's magnetic field secular variation at a station under the northern crest of the equatorial ionization anomaly
(American Geophysical Union, 2016-01)
Long-term trend of the critical frequency of the F2 ionospheric region, foF2, at Phu Thuy station (21.03°N, 105.96°E), Vietnam, located under the northern crest of the equatorial ionization anomaly, EIA, is studied. Annual ...
Trends in the F2 ionospheric layer due to long-term variations in the Earth's magnetic field
(Elsevier, 2009-06)
The Earth's magnetic field presents long-term variations with changes in strength and orientation. Particularly, changes in the dip angle (I) and, consequently, in the sin(I)cos(I) factor, affect the thermospheric neutral ...

Long-term changes in solar quiet (Sq) geomagnetic variations related to Earth?s magnetic field secular variation
(American Geophysical Union, 2013-01)
The daily amplitude of the solar quiet (Sq) magnetic variation of the horizontal intensity, H, of observatories at low and midlatitudes is analyzed, in search of significant long‐term trends. These trends are expected based ...
