| Zusammenfassung |
| A comprehensive error characterization of SCIAMACHY (Scanning
Imaging Absorption Spectrometer for Atmospheric CHartographY) limb
ozone profiles has been established based upon SCIATRAN transfer
model simulations. The study was carried out in order to evaluate
the possible impact of parameter uncertainties, e.g. in albedo,
stratospheric aerosol optical extinction, temperature, pressure,
pointing, and ozone absorption cross section on the limb ozone
retrieval. Together with the a posteriori covariance matrix
available from the retrieval, total random and systematic errors are
defined for SCIAMACHY ozone profiles. Main error sources are the
pointing errors, errors in the knowledge of stratospheric aerosol
parameters, and cloud interference. Systematic errors are of the
order of 7%, while the random error amounts to 10–15% for most
of the stratosphere. These numbers
can be used for the interpretation of instrument intercomparison and
validation of the SCIAMACHY V 2.5 limb ozone profiles in a rigorous
manner. |
