AB: This paper describes global stratospheric variations in HCl, as observed by the Earth Observing System (EOS) Microwave Limb Sounder (MLS) aboard the satellite Aura, after more than one year of continuous global measurements. Comparisons versus the SLIMCAT 3-D model will highlight any unexpected changes in the stratosphere. Data continuity and quality issues are investigated by analyzing HCl data from MLS, HALOE, and ACE, along with other supporting data products. We discuss implications of surface chlorine measurement comparisons to the high precision global HCl abundances obtained from MLS in the upper stratosphere and lower mesosphere.
