| Zusammenfassung |
| The VIMS instrument onboard Cassini observed the north polar region the 28th december
2006, and detected a vast polar cloud. Aside from this cloud, the observation also gives
information about the haze layer in this region. The data that we use do not allow to probe
down to the surface. In this work, we characterized the stratosphere haze layer, the
troposphere scatterers and the polar cloud. We give new constraints about the optical constant
of the aerosol material around 2.8 μm, and we are able to draw a new spectral behaviour for
the haze refractive index between about 0.4 and 4.0 μm from various sources. We also
indentify the origin of spectral features in the 2.8 μm methane window, which are mainly due
to CH3D. |
