Incoherent scatter spectrum theory for modes propagating perpendicular to the geomagnetic field
(American Geophysical Union, 2006-06-20)
The short‐term relationship of the equatorial peak electron density and the solar short‐wavelength irradiance is examined using foF2 observations from Jicamarca, Peru and recent solar irradiance measurements from satellites. ...
Latitudinal variation of foF2 hysteresis of solar cycles 20, 21 and 22 and its application to the analysis of long-term trends
(Copernicus Publications, 2008-12)
F2 monthly median values for equinoctial months of solar cycles 20, 21 and 22, were analyzed for 37 worldwide stations. For each solar cycle and for a given , the difference between F2 in the falling branch of the cycle ...
Comparison of F1 layer critical frequency between recent two solar minimums
(American Geophysical Union, 2016-09-06)
This study compares the F1 layer critical frequencies (foF1) between the 22/23 and 23/24 solar minimums to investigate the effects of extremely low solar activities on F1 layer. The foF1 data of 1996 and 2008 at various ...
Ionospheric disturbances at low and mid-low latitudes of the South American sector during the March 2015 great storm
(Elsevier, 2019-06)
This paper analyzes the response of the near equatorial and low latitude ionosphere of the South American sector to the geomagnetic storm occurred on 17 March 2015. Ionosonde data from Ramey (18.5° N, 292.9° E), Jicamarca ...
Perturbaciones ionosféricas durante tormentas geomagnéticas en altas latitudesIonospheric disturbances at high latitudes during geomagnetic storms
(Asociación Argentina de Geofísicos y Geodestas, 2016-11)
En este trabajo se analiza el comportamiento de la ionosfera sobre una estación de alta latitud durante algunas tormentas geomagnéticas intensas ocurridas en 2000 y 2001. Para ello, se utilizan datos de la frecuencia crítica ...
