| Zusammenfassung |
| Stratospheric aerosols are of a great scientific interest because of their crucial role in the
Earth’s radiative budget as well as their contribution to chemical processes resulting in ozone
depletion. While the permanent aerosol background in the stratosphere is determined by the
tropical injection of SO2, COS and sulphate particles from the troposphere, major
perturbations of the stratospheric aerosol layer result form an uplift of SO2 after strong
volcanic eruptions. Satellite measurements in the visible spectral range represent one of the
most important sources of information about the vertical distribution of the stratospheric
aerosol on the global scale. This study employs measurements of the scattered solar light
performed in the limb viewing geometry from the space borne spectrometer SCIAMACHY,
which operated onboard the ENVISAT satellite from August 2002 to April 2012.
A progress in the development of SCIAMACHY aerosol data product within the
ROSA/ROMIC project including the improvements in the extinction coefficient data base
and steps towards the retrieval of particle size distribution parameters is reported. |
