Ground-based measurements of scattered light were collected in the Antarctic fall, winter, and spring at McMurdo Station during the winter and spring of 1991. These measurements yielded values of the slant column amounts of the dioxides of chlorine and nitrogen found in the stratosphere. Two different viewing schemes were used to collect this data; a zenith viewing mode to collect light scattered from directly overhead, and a new off-axis viewing mode to collect light scattered along a path at 80 degree(s) zenith angle toward the sun. This new viewing geometry allowed measurements to be made much further into twilight and polar winter than was previously possible with only the zenith viewing mode. Results of this analysis showed that OClO levels were very high in late July and early August, declining through September, and dropping below detection levels in early October.
