| Zusammenfassung |
| An important new challenge in the field of multi-angle
photo-polarimetric satellite remote sensing is the retrieval of aerosol
properties under cloudy conditions. In this paper the possibility has
been explored to perform a simultaneous retrieval of aerosol and cloud
properties for partly cloudy scenes and for fully cloudy scenes where
the aerosol layer is located above the cloud, using multi-angle
photo-polarimetric measurements. Also, for clear sky conditions a
review is given of the capabilities of multi-angle photo-polarimetric
measurements in comparison with other measurement types. It is shown
that already for clear sky conditions polarization measurements
are highly important for the retrieval of aerosol optical and
microphysical properties
over land surfaces with unknown reflection properties. Furthermore,
it is shown that multi-angle photo-polarimetric measurements
have the capability to distinguish between aerosols and clouds,
and thus facilitate a simultaneous retrieval of aerosol and
cloud properties. High accuracy (0.002–0.004)
of the polarimetric measurements plays an essential role here. |
