Sentence examples for minimum virtual height from inspiring English sources

minimum virtual height of F layer.

We have also plotted the minimum virtual height of the bottomside F layer (h'F), which is shown as a gray curve.

Rastogi (1978) presented one example (26 April 1971) in which he compared the upward transport velocity (V z F), measured with the IS radar, to the minimum virtual height (h'F) versus LT, measured with the ionosonde.

We have further investigated changes in the different ionospheric F-region parameters (minimum virtual height of the F-region (h′F), virtual height at 0.834foF2 (hpF2), and foF2) during summer to winter months in low solar activity periods, 2006 2007 and 2007 2008.

The seasonal mean variations (using only geomagnetically quiet days) of the ionospheric parameters foF2 (critical frequency of the F-region), hpF2 (virtual height at 0.834 foF2; considered to be close to hmF2 (peak height of the F-region)), and h'F (minimum virtual height of the F-region) are calculated and compared between PAL and SJC.

the virtual height of the bottom-side F-layer.

This result implies that the peak height hmF2 derived from the virtual height through true height analysis based on Titheridge method seems to underestimate the true peak height.

As an estimate for the virtual height of the bottomside F layer, they scaled the virtual height at 2.5 MHz [i.e., h'(2.5)].

The most noticeable effect on the virtual height is that at farther ranges, instead of becoming nearly constant, the derived virtual height increases monotonically.

Magnified Fig. 2 by zooming the sounding frequency (1 7 MHz) and virtual height (0 400 km).

Simulating a perfect reflector at an altitude equal to the virtual height of reflection, the virtual time delay is assumed as a real time delay.
