The OSIRIS instrument on the Odin satellite provides observations of both the airglow and the scattered sunlight
limb spectra, over the wavelength range 280 – 810 nm. While the recorded spectra only have a 1 nm resolution it
is possible to identify many highly structured emissions in the measured spectra. These spectra also contain the
unambiguous signature of the PMCs. The spectrograph observations within these clouds also provide clear
measurements of the oxygen atmospheric A-, B- and g-bands that can be used to provide common volume
information of temperature and cloud brightness. In this paper we present some of the initial estimates of the
atmospheric temperature within PMCs derived from the OSIRIS PMC observations.
