Importantly, spatio-temporal characteristics of IS are subject to different kinds of plasma instabilities which may or may not be present in the radar's field-of-view, in contrast to the regular ground scatter (GS) echoes, which represent radio waves "reflected" by the regular ionospheric layer before they are scattered back by the rugged ground surface.
Though we had passed over not less than four-and-twenty miles of very rugged ground, and had a Highland dance on the top of Dùn Can, the highest mountain in the island, we returned in the evening not at all fatigued, and piqued ourselves at not being outdone at the nightly ball by our less active friends, who had remained at home.
In the Cph1Δ Pfr state, which has a low quantum yield, the need for two GSI populations in the target model suggests a rugged ground-state potential energy surface and raises the possibility of unproductive depopulation of the excited state to generate GSI species.
The area consisted of "very difficult and broken ground" in a rugged area of the Judean Hills.
His response to frippery like gazebos isn't surprising, given his rugged training grounds.
But this is a coastline whose mystique goes way beyond cine-tourism; it's a place of looming purple mountains topped with snow and grey-tinged landscapes hiding Viking burial grounds, rugged cod fishing communities and legends of trolls.
He became a powerful and often controversial full-forward, and some of his rugged exchanges on the ground led to Tribunal suspensions.
Additional new sites in rugged terrain still require ground verification.
Finally, rugged terrain provides excellent ground for the children to explore and play in, unlike the wetter low-lying flats so dominant in the tundra (Figure 12).
Extra-terrestrial landscapes or a collapsed rubble environment, ubiquitous to war and disaster zones, will contain regions of highly rugged yet relatively level ground.
