Satellite remote sensing of atmospheric O/N2 using the Coronas - F data
Abstract
Simultaneous measurements of disk-viewing of the 0.842, 17.5 and 30.4-nm obtained on the board of the Coronas - F spacecraft are used to monitor the ratio of the atomic oxygen density to the molecular nitrogen density (O/N2 ). The technique for deriving atmospheric O/N2 values from observations of solar emission is described. The O/N2 relation obtained directly from far ultraviolet data is in good agreement with parameters of the Earth's upper atmosphere calculated by models. The results illustrate the potential of the technique for monitoring atmospheric dynamics through latitudinal and temporal variations in O/N2 which are signatures of ascending and decending motion in the atmosphere. The value of this work is in providing a signature of the atmospheric dynamics that can be obtained directly from disk images.
