Technical Note: A SAGE-corrected SBUV zonal-mean ozone data set Environment Canada, Toronto, Canada
Received: 16 Apr 2009 – Published in Atmos. Chem. Phys. Discuss.: 20 May 2009Abstract. A stratospheric vertically resolved, monthly, zonal-mean ozone data set
based on Satellite Aerosol and Gas Experiment (SAGE) and Solar Backscatter
UltraViolet (SBUV) data spanning 1979–2005 is presented. Drifts in
individual SBUV instruments and inter-SBUV biases are corrected using SAGE I
and II by calculating differences between coincident SAGE-SBUV measurements.
In this way the daily, near-global coverage of SBUV(/2) is combined with the
stability and precision of SAGE to provide a homogeneous ozone record
suitable for trend analysis. The resultant SAGE-corrected SBUV data set,
shows, for example, a more realistic Quasi-Biennial Oscillation signal
compared to the one derived from SBUV data alone. Furthermore, this
methodology can be used to extend the present data set beyond the lifetime
of SAGE II.
