Zusammenfassung |
For the retrieval of the vertical distribution of ozone in the
atmosphere the Ozone ProfilE Retrieval Algorithm (OPERA) has been
further developed. The new version (1.26) of OPERA is capable of
retrieving ozone profiles from UV–VIS observations of most nadir-looking satellite instruments like GOME, SCIAMACHY, OMI and
GOME-2. The setup of OPERA is described and results are presented for
GOME and GOME-2 observations. The retrieved ozone profiles are
globally compared to ozone sondes for the years 1997 and 2008. Relative
differences between GOME/GOME-2 and ozone sondes are within the limits
as specified by the user requirements from the Climate Change
Initiative (CCI) programme of ESA (20% in the troposphere,
15% in the stratosphere). To demonstrate the performance of
the algorithm under extreme circumstances, the 2009 Antarctic ozone
hole season was investigated in more detail using GOME-2 ozone
profiles and lidar data, which showed an unusual persistence of the
vortex over the Río Gallegos observing station (51° S,
69.3° W). By applying OPERA to multiple instruments,
a time series of ozone profiles from 1996 to 2013 from a single robust
algorithm can be created. |
