Figure 4. (a) Computed Quenching coefficient for the
28 pulses and also at the point of the reflection one instant before and
after the HF transmitters were turned off. (b)N2 concentration provided by the NRLMSISE-00 (dots) and
the ones retrieved using the O(1D) lifetime.
(c) Ratio between the N2 retrieved concentrations by the
NRLMSISE-00’s concentration for the same altitudes.
