Total ozone measured during EASOE by a UV-visible spectrometer which observes stars
Total ozone was measured from Abisko, Sweden (68.4°N, 18.8°E) from January to early March 1992, by a new instrument which uses stars and the Moon as sources of UV-visible light for absorption spectroscopy. In addition, some zenith-sky observations were made. Ozone measurements obtained using both techniques are presented and compared with those from other instruments. Good agreement with simultaneous ozonesonde measurements is observed, but the stellar measurements appear systematically higher than total ozone measured by both SAOZ and TOMS.
