AB: MAESTRO (Measurement of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation) is a UV-visible spectrometer performing solar occultations and nadir backscatter measurements on board ACE (Atmospheric Chemistry Experiment, or SCI-SAT I) since August 2003. In this paper we present an introduction to the MAESTRO instrument and retrieval algorithms and a comparison of MAESTRO O$_3$ and NO$_2$ profiles with coincident OSIRIS (Optical Spectrograph and Infrared Imager System) measurements. To faciltate the comparison, OSIRIS NO$_2$ profiles have been shifted from their local time to a SZA of 90$^\deg$ using a photochemical model.
