Data Access Data Format
Measurements and Applications UV spectrometry of the ionosphere performed under 3 different viewing angles. Observation of the night-sky 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 oxygen air glow intensity and the nitrogen air glow intensity of LBH (sensitivity=1 counts.s-1.R-1) for the retrieval of oxygen-nitrogen ratio at the ionospheric altitude. Three units which point in different directions
