Disturbances in the F1 ionospheric layer in April 2005
Abstract
Manifestations of ionospheric disturbances at heights from 120 km to the height h m of the F2-layer maximum are analyzed. The geomagnetic disturbances on April 5, 12, and 13, 2005, are considered. These disturbances are characterized by a pronounced synchronous decrease in the electron concentration over the entire indicated height range. Using the method proposed by the authors, the noontime changes in the relative content of atomic and molecular oxygen at a height of 120 km are estimated. There are a distinct decrease in the ratio of atomic oxygen and molecular nitrogen concentrations and an increase in the ratio of oxygen molecule and atom concentrations.
