| Zusammenfassung |
| In this paper, the latest SCIAMACHY limb ozone scientific vertical
profiles, namely the current V2.9 and the upcoming V3.0, are extensively
compared with ozonesonde data from the World Ozone and Ultraviolet Radiation
Data Centre (WOUDC) database. The comparisons are made on a global scale from
2003 to 2011, involving 61 sonde stations. The retrieval processors used to
generate V2.9 and V3.0 data sets are briefly introduced. The comparisons are
discussed in terms of vertical profiles and stratospheric partial columns.
Our results indicate that the V2.9 ozone profile data between 20 and 30 km
are in good agreement with ground-based measurements, with less than 5 %
relative differences in the latitude range of 90° S–40° N
(with the exception of the tropical Pacific region, where an overestimation of
more than 10 % is observed), which corresponds to less than 5 DU
partial-column differences. In the tropics the differences are within 3 %.
However, this data set shows a significant underestimation northwards of
40° N (up to ~ 15 %). The newly developed V3.0 data set
reduces this bias to below 10 % while maintaining a good agreement
southwards of 40° N with slightly increased relative differences of
up to 5 % in the tropics. |
