Abstract
The International Space Station/Japanese Exposure Module (ISS/JEM) borne instrument, the Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES), has successfully measured chemical species in the middle atmosphere between October 2009 and April 2010. We focus on inorganic chlorine species measured inside the late spring Antarctic vortex, when hydrogen chloride (HCl) was a main component of the total inorganic chlorine (Cly). Comparisons with other satellite instruments, the Aura Microwave Limb Sounder (MLS) and Atmospheric Chemistry Experiment Fourier transform spectrometer (ACE-FTS), are also presented to show the SMILES HCl and chlorine monoxide (ClO) data quality.
