摘要: The dependence in altitude and time of the ionospheric electron density its variations during solar eclipse August 11, 1999, have been studied. true height profiles recorded at Observatori de l'Ebre station (40.8° N, 0.5° E) a rapid sequence vertical sounding campaign used. A gravity wave like oscillation ionosphere has characterized after maximum occultation by Moon. event is clearly seen both plasma frequency F region range from 150 to 250 km, it dominant oscillating period T=57.5 min. activity linked with found exist parameters, being coherent oscillations variations. source-origin was located around transition between F1 F2 layers that propagates vertically drawing energy upwards downwards simultaneously. decreasing/increasing ionizing radiation cooling/heating processes are discussed as possible mechanism explain observed dynamics ionosphere.
