========================================================================= ==> time for this proposal is to be transferred from acousten.titan a ==> this proposal requests an upgrade from priority 3 for acousten.titan a ========================================================================= we propose to record the short-wavelength spectrum of titan between 2 and 9 micron with cam-cvf and between 2 and 12 micron with phot-s. some of these regions of very low flux (in particular the 4-5 mu region) cannot be observed with sws with sufficient s/n. these data will provide information about the lower troposphere and the surface of titan, in particular in the windows around 2.5-3.2mu and 4-5mu, very difficult to access from the ground. the 5-7mu region will provide data on a completely unexplored region of the spectrum, where both the reflected sunlight and the thermal emission contribute to the spectrum. pht-s and cam data are highly complementary, as the pht-s data extend up to 12 mu, whereas the cam data cover the 5-6 mu region. in addition, the cam data will allow for a better correction of saturn.s straylight contamination. observations will be performed at titan.s maximum eastern elongation, where more flux is expected than elsewhere on the orbit. the pht-s observation of titan was already planned in the central program proposal of coustenis et al (acousten.titan a), with priority 3. we propose to transfer the time allocated to acousten.titan a (7200 s) and to this proposal with priority 1.

Mission Description
The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
