Measurements and Applications
Observation of the night-sky 135.6 nm oxygen airglow intensity for the retrieval of ionospheric total electrons and NmF2 (sensitivity ≥150 counts.s-1.R-1); and observation of the bright-day 135.6 nm oxygen air glow intensity and the nitrogen air glow intensity of LBH (140-180 nm）(sensitivity≥1 counts.s-1.R-1) for the retrieval of oxygen-nitrogen ratio at the ionospheric altitude.
