| Zusammenfassung |
| Remote sensing of aerosol from space is a challenging and typically
underdetermined retrieval task, requiring many assumptions to be made
with respect to the aerosol and surface models. Therefore, the quality
of a priori information plays a central role in any retrieval process
(apart from the cloud screening procedure and the forward radiative
transfer model, which to be most accurate should include the treatment
of light polarization and molecular-aerosol coupling). In this paper
the performance of various algorithms with respect to the of spectral aerosol optical thickness determination from optical spaceborne
measurements is studied. The algorithms are based on various types of
measurements (spectral, angular, polarization, or some combination of
these). It is confirmed that multiangular spectropolarimetric
measurements provide more powerful constraints compared to spectral
intensity measurements alone, particularly those acquired at a single
view angle and which rely on a priori assumptions regarding the
particle phase function in the retrieval process. |
