Characteristic spectral aspects of a Martian duststorm
C. Muller and D. Moreau
Belgian Institute for Space Aeronomy
Computed spectra of a Martian atmosphere transmission as observed by
the ISO SWS in the case of a Martian duststorm will be shown for several
levels of dust altitude. Dust composition and spectral response will also be
discussed. As the historical Martian storm season begins only at the middle
of October 1997, and as the 1997 Mars ISO Mars opportunity has ended at the end
of August without any global duststorm occurence, no actual ISO data will be
presented. The origin and nature of the dust storms will be discussed as well
as their global consequences on the Mars atmospheric system on the basis of a
mathematical model.
