Abstract
The Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE‐FTS) is the primary instrument for the ACE satellite mission. The initial validation of ozone profiles from ACE‐FTS is based on comparisons with profiles from satellite‐borne instruments and balloon‐borne ozonesondes. The satellite instruments include the SAGE III and POAM III instruments. The ACE profiles were recorded during March 2004 at high latitudes in the northern hemisphere (>65°N) and were processed with the version 1.0 retrieval algorithm. The ACE‐FTS results were found to agree within 10% with those from the other satellite measurements between 15 and 40 km, with ACE‐FTS measuring less ozone near the profile maximum. The ACE‐FTS has a lower vertical resolution than SAGE III or POAM III and this may contribute to the observed discrepancy. The comparisons with ozonesonde measurements suggest that the ACE‐FTS accurately captures vertical structures in the ozone profile that are on the order of several kilometers thick.Keywords
