AB: A second-generation Microwave Limb Sounder (MLS) was launched as part of NASA's Earth Observing System (EOS) Aura mission in July 2004. EOS MLS measures several more stratospheric species than did its predecessor on the Upper Atmosphere Research Satellite (UARS). Simultaneous measurements of temperature, N$_2$O, HNO$_3$, H$_2$O, HCl, ClO, and O$_3$ provide a much more complete picture of polar processing and chemical ozone destruction in the stratosphere than has previously been possible. EOS MLS measurements of these species will be used to track the evolution of chlorine deactivation, denitrification, dehydration, and ozone loss through the 2004 Antarctic late winter and spring period.
