Zusammenfassung |
Venus Express is now entering its eighth year of operation in Venusian orbit. Among the still
working instruments, all three channels of the SPICAV [Bertaux et al., 2007] spectrometer
are still fully working and routinely provide new insights on the Venusian atmosphere. We
propose to review and highlight the results and the work in progress, among which
(non-exhaustive list):
a new mapping of the nightside airglow of nitric oxide (NO) using the nadir
mode of SPICAV-UV ;
the first detection of the dayglow due to CO and CO2+ using limb observations
of SPICAV-UV [Chaufray et al., 2012] ;
the secular evolution of SO2 column density above Venus’ cloud top using
SPICAV-UV in nadir mode [Marcq et al., 2013] ;
polarimetric and phase function studies of the upper clouds of Venus using
SPICAV-IR.
