GOME/SCIAMACHY/GOME2 Merged Total Ozone
Data access
In the merged GOME/SCIA/GOME2 data set, the
following data are included:
- GOME (July 1995 - May 2003) without adjustments
- SCIAMACHY (June 2003 - March 2012) with bias adjustments
- GOME2/Metop A (March 2013 - ) with bias adjustments
Figure: Total ozone time series from different
merged datasets. The pink line indicates the estimated ozone change due
to changes in stratospheric halogen. From Weber et al. (2013).
Additional comments
The WFDOAS total algorithms are described in
Coldwey-Egbers et al. (2005). Validation results have been reported by
Bracher et al. (2005), Weber et al. (2005), and Fioletov et
al. (2008).
There are other total ozone algorithm available for
GOME's and SCIAMACHY as follows:
- ESA/DLR operational retrieval (Roozendael et al. 2006, Balis et al., 2007, Anton et al., 2009)
- KNMI retrieval including data assimilation (Eskes et al., 2005)
A merged data set from the ESA/DLR retrievals were
reported by Loyola et al. (2009).
A description of the satellite instruments GOME, SCIAMACHY, and GOME2
can be found in Bovensmann et al. (1999), Burrows et al. (1999), and
Callies et al. (2000), respectively.
