Abstract. This paper details the SAGE (Stratospheric Aerosol and Gas Experiment) version 7.0 algorithm and how it is applied to SAGE II. Changes made between the previous (v6.2) and current (v7.0) versions are described and their impacts on the data products explained for both coincident event comparisons and time-series analysis. Users of the data will notice a general improvement in all of the SAGE II data products, which are now in better agreement with more modern data sets (e.g., SAGE III) and more robust for use with trend studies.
