GPS TEC and ITEC from digisonde data compared with NEQUICK model [PDF]
Advances in Radio Science, 2004 At the Dourbes station, a digisonde 256 is colocated with a Turbo Rogue GPS receiver. Real time processing of the digisonde data gives the electron density profile and the ITEC value (SAO file) for each sounding.

Concurrent study of bottomside spread F and plasma bubble events in the equatorial ionosphere during solar maximum using digisonde and ROCSAT-1 [PDF]
Annales Geophysicae, 2005 Data from the Jicamarca digisonde and the ROCSAT-1 satellite are employed to study the equatorial ionosphere on the west side of South America during April 1999-March 2000 for the concurrent bottomside spread F (BSSF) and plasma bubble events.

The intensification of metallic layered phenomena above thunderstorms through the modulation of atmospheric tides. [PDF]
Sci Rep, 2019 We present a multi-instrument experiment to study the effects of tropospheric thunderstorms on the mesopause region and the lower ionosphere. Sodium (Na) lidar and ionospheric observations by two digital ionospheric sounders are used to study the ...

Comparison of COSMIC measurements with the IRI-2007 model over the eastern Mediterranean region [PDF]
Journal of Advanced Research, 2013 This paper presents a comparison of the International Reference Ionosphere (IRI-2007) model over the eastern Mediterranean region with peak ionospheric characteristics (foF2–hmF2) and electron density profiles measured by FORMOSAT-3/COSMIC satellites in ...

Automated collection and dissemination of ionospheric data from the digisonde network [PDF]
Advances in Radio Science, 2005 Abstract. The growing demand for fast access to accurate ionospheric electron density profiles and ionospheric characteristics calls for efficient dissemination of data from the many ionosondes operating around the globe. The global digisonde network with over 70 stations takes advantage of the Internet to make many of these sounders remotely ...
