| 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 retrieval approach to obtain parameters of the stratospheric aerosol particle
size distribution will be reported along with the sensitivity studies and first results. |
