f sub(o)F sub(2) long-term trend linked to Earth's magnetic field secular variation at a station under the northern crest of the equatorial ionization anomaly
Long-term trend of the critical frequency of the F sub(2) ionospheric region, f sub(o)F sub(2) , at Phu Thuy station (21.03 degree N, 105.96 degree E), Vietnam, located under the northern crest of the equatorial ionization anomaly, EIA, is studied. Annual mean data are analyzed at 04 LT and 12 LT fo...

Zusammenfassung: | Long-term trend of the critical frequency of the F sub(2) ionospheric region, f sub(o)F sub(2) , at Phu Thuy station (21.03 degree N, 105.96 degree E), Vietnam, located under the northern crest of the equatorial ionization anomaly, EIA, is studied. Annual mean data are analyzed at 04 LT and 12 LT for the period 1962-2002 using monthly median values and monthly mean values during magnetically quiet days (am |
