A global model of the ionospheric F2 peak height based on EOF analysis
The ionospheric F2 peak height hmF2 is an important parameter that is much needed in ionospheric research and practical applications. In this paper, an attempt is made to develop a global model of hmF2. The hmF2 data, used to construct the global model, are converted from the monthly median hourly values of the ionospheric propagation factor M(3000)F2 observed by ionosondes/digisondes distribut...
متن کاملQuiet-condition variations in the scale height at F2-layer peak at Jicamarca during solar minimum and maximum
This study is the first attempt to examine the quiet-condition variations in scale height (Hm) near the F2layer peak in the equatorial ionosphere. The data periods of Hm derived from the Jicamarca ionograms are JanuaryDecember 1996 and April 1999–March 2000. The results show that the greatest and smallest Hm values are generally at 11:00–12:00 LT and 04:00–05:00 LT, respectively. Additionally, ...
متن کاملEffect of Seasonal Anomaly or Winter on The Refractive Index of in Height of The Ionospheric F2-Peak
In this paper, we deal with the effect on the refractive index of seasonal anomaly in height of the ionospheric F2 peak for both, collisional and collisionless cases in the by using the real geometry of Earth’s magnetic field for north hemisphere. It is possible to say that there is an anti-symmetric harmony between the electron density and the all waves (for collisional and collisionless cases...
متن کاملLong-term comparison of the ionospheric F2 layer electron density peak derived from ionosonde data and Formosat-3/COSMIC occultations
Electron density profiles (EDPs) derived from GNSS radio occultation (RO) measurements provide valuable information on the vertical electron density structure of the ionosphere and, among others, allow the extraction of key parameters such as the maximum electron density NmF2 and the corresponding peak height hmF2 of the F2 layer. An efficient electron density retrieval method, developed at the...
متن کاملVariability of F2-layer peak characteristics at low latitude in Argentina for high and low solar activity and comparison with the IRI-2016 model
This work presents the study of the variability of foF2 and hmF2 at a low latitude station in South America (Tucumán, 26.9°S, 294.6°E; magnetic latitude 15.5°S, Argentina). Ground based ionosonde measurements obtained during different seasonal and solar activity conditions (a year of low solar activity, 2009 and one of high solar activity, 2016) are considered in order to compare the ionospheri...
