Abstract
UARS MLS measurements of lower stratospheric ClO during the 1992-93 an d 1993-94 Arctic winters are presented. Enhanced ClO in the 1992-93 wi nter was first observed in early December, and extensively during Febr uary when temperatures were continually low enough for PSCs. Sporadic episodes of enhanced ClO were observed for most of the 1993-94 winter as minimum temperatures hovered near the PSC threshold, with largest C lO amounts occurring in early March after a sudden deep cooling in lat e February.
