AB: The suite of solar occultation instruments collecting data on polar stratospheric clouds (PSCs) now includes SAGE III, which began routine operations on the Russian Meteor-3M spacecraft in late February 2002. SAGE III sunset data are collected from 65N-80N during local winter; hence, the likelihood of Arctic PSC observations is high. There is a much smaller (but not zero) probability of observing PSCs in the Southern Hemisphere since the latitude range for local (sunrise) data collection during austral winter is only 50S-60S. This talk will present SAGE III PSC observations from the 2002-2003 Arctic winter, and compare them to the relatively few PSCs observed by the instrument in the Southern Hemisphere during 2002 and 2003. A focus of the talk will be the ability to distinguish PSC types by using multiple-wavelength SAGE III extinction data.
