Southern high-latitude Digisonde observations of ionosphere E-region Bragg scatter during intense lacuna conditions [PDF]
Annales Geophysicae, 2004 During summer months at solar cycle minimum, F-region lacuna and slant-Es conditions (SEC) are common features of daytime ionograms recorded around local magnetic noon at Casey, Antarctica. Digisonde measurements of drift velocity height profiles show

Exploring the occurrence rate of PMSE-Es by Digisonde at Tromsø
Earth and Planetary Physics, 2021 Polar mesosphere summer echoes (PMSE) are observed simultaneously with Digisonde and EISCAT VHF radar. The phenomenon of irregular Es layers is called PMSE-like or PMSE-Es (Polar Mesosphere Summer Echoes-Es) and has some relationship with real PMSE.

On the use of high-frequency surface wave oceanographic research radars as bistatic single-frequency oblique ionospheric sounders [PDF]
Atmospheric Measurement Techniques, 2022 We demonstrate that bistatic reception of high-frequency oceanographic radars can be used as single-frequency oblique ionospheric sounders. We develop methods that are agnostic of the software-defined radio system to estimate the group range from the ...
