AB: Two springtime validation campaigns have been conducted in the Canadian Arctic to provide correlative measurements for validating results from the Atmospheric Chemistry Experiment (ACE) satellite mission. The satellite has two instruments on-board: a high-resolution infrared Fourier Transform Spectrometer (ACE-FTS) and a dual UV-visible-NIR spectrophotometer called MAESTRO (Measurement of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation). The validation campaigns took place at Environment Canada's Arctic Stratospheric Ozone (AStrO) Observatory in Eureka, Nunavut (80 N, 86 W) between February and April in both 2004 and 2005. Seven ground-based instruments were operated during the 2004 campaign: a ground-based adaptation of the ACE-FTS (PARIS - Portable Atmospheric Research Interferometric Spectrometer), a ground-based version of the ACE-MAESTRO, a SunPhotoSpectrometer, a zenith-viewing UV-visible grating spectrometer, a Bomem DA8 Fourier transform spectrometer, a Differential Absorption Lidar and a Brewer spectrophotometer. For the 2005 campaign, a Systeme d'Analyse par Observations Zenithales (SAOZ) instrument and a second Brewer were added to the instrument complement. Also, balloon-borne ozonesonde and radiosonde sensors were flown frequently during both campaigns. This paper will focus on comparisons of ozone measurements made by the ground-based, balloon-borne and satellite-borne instruments during the two ACE Arctic Validation campaigns. Comparisons of both retrieved columns and profiles will be presented. Also, the results from the 2004 and 2005 campaigns will be intercompared to highlight the differences between the two years.
