In this paper, we compared the F2-Layer critical frequency (foF2) derived from FORMOSAT-3/COSMIC radio occultation (RO) and ionosondes at Chiang Mai, Chumphon and Kototabang during the years 2008–2015 to evaluate the performance of COSMIC RO over ...

Travelling Ionospheric Disturbances (TIDs) are ionospheric signatures of atmospheric gravity waves. They can result from a variety of natural or artificial sources. Their identification and tracking is important because the TIDs affect all services that rely on predictable ionospheric radio wave propagation.

From ionosonde to rocket sonde
Journal of Geophysical Research: Space Physics, 1994The 75th Anniversary of the AGU marks the discovery of the basic features of solar control of the ionosphere. A quarter of a century later our understanding of ionospheric physics was revolutionized by the early rocket era of upper air research that brought the discoveries of solar X ray and XUV radiation.

Ionosonde observations of daytime spread F at middle latitudes during a geomagnetic storm
Journal of Atmospheric and Solar-Terrestrial Physics, 2018Recently, Jiang et al., (2016) reported daytime spread F at Puer station (22.7oN, 101.05oE, Dip Lat 12.9oN). As a continual work, daytime spread F at middle latitudes was investigated in this study through ionograms recorded by an ionosonde installed at ...

Using the Swedish Ionosonde Network
Sixth International Conference on `HF Radio Systems and Techniques', 1994The three vertical ionosondes operated by the Swedish Institute of Space Physics have been modernized and integrated with a data network. They are collectively called SIN, the Swedish Ionosonde Network. The authors describe a graphical user interface for running and displaying results from the ionosondes.

Simulation of ionosonde observations of ionospheric holes
Journal of Atmospheric and Terrestrial Physics, 1992Abstract When conducting active experiments in the ionosphere which give rise to artificial disturbances of electron density, it is necessary to diagnose such disturbances. The study of irregularities using groundbased radio sounding methods often involves recording and analyzing ionogram traces, depending on the position, dynamics and phase of ...

Quantifying spread F by digital ionosondes
Advances in Space Research, 2003The width of frequency-spreading (Δff) on ionograms was shown (Wright, et al., 1977, by comparison with OGO-6 Satellite observations) to be proportional to ΔNN near and above the F-region peak. Thus, even classical analog ionograms using logarithmic frequency scales were direct reading for this important parameter, although little use has been made of ...
