In this paper, we present the first global comparisons between the two unique satellite-borne data sets of nitrogen trioxide (NO 3 ) vertical profiles retrieved from the GO-MOS (Global Ozone Monitoring by the Occultation of Stars) stellar occultations and the SAGE III (Stratospheric Aerosol and Gas Experiment) lunar occultations. The comparison results indicate that between the altitudes 25 km and 45 km the median difference between these two data sets is within ±25 %. The study of zonal median

No clear systematic differences are observed. The median profiles are closest in the tropics and slightly deviating at high latitudes.
