| Zusammenfassung |
| The climatology of the aerosol loading in the mesosphere of Venus is investigated from data
obtained with SOIR, a channel of the SPICAV instrument suite on-board Venus
Express.
Although SOIR alone is less informative in terms of micro-physical properties of the
particles than the use of all three channels of the instrument, a large set of data has now been
accumulated with the SOIR channel allowing the study of geo-temporal variability of the
upper haze.
Vertical profiles of the aerosol extinction are retrieved from a spectral window around
3.0 μm recorded in many solar occultations (~ 200) from September 2006 till September
2010. For this period, the continuum of light absorption is analyzed in terms of spatial and
temporal variations of the upper haze of Venus. |
