Link to Cassini T78 page: http://saturn.jpl.nasa.gov/mission/flybys/titan20110912/

Much more info on the CICLOPS Looking ahead page (entire 3rd paragraph): http://www.ciclops.org/view/6866/Rev153
CIRS (longer wave IR) South Polar high latitude chemical measurements
UVIS upper atmosphere nitrogen profile (proxy for pressure/temperature - used to normalize atmospheric measurements from CIRS)
UVIS [deuterium absorption cell] H to D ratio (H-H vs H-D molecular transitions or atomic transitions of H. vs D. ?)

This'll be really exciting to compare with previous flyby data acquired nearer to the solstice.
How is the south polar atmosphere cooling?
How about the concentrations of the different chemical species? - they were pretty bland and uniform at the South Pole during southern pole summer, but pretty exciting and zonal at the north pole winter. Is the south polar atmosphere starting to create zones as it transitions to winter?

Stay tuned...
