frequency, up to 16-17 MHz. After all, the sun was more overhead for there and the solar UV had less atmosphere to penetrate. But at larger zenith angles, particularly toward the polar regions, the critical frequencies would be lower, going down to 6-7 MHz. All that for a SSN of ...
As a final note, I chose to title some of my publications "polar excision" for historical reasons although it has nothing to do with polarization filtering or excision. That is usually a linear adaptive filter --totally different thing. Instead, my use of polar refers to the IQ complex-plan...
Atomic radius, crystal structure, electronegativity, and the most common valence are given in the following table for the several elements; for those that are nonmetals, only atomic radii are indicate Why it is important to have ...
International Reference Ionosphere (IRI) 2012 model (Bilitza et al.2014) is 146–350 km. Criteria chosen for selecting events described in “Data analysis” subsection led to a non-uniform distribution in the analyzed GWs with respect to LT and season, which influenced the obtained statistical ...
