The Millimeter wave Atmospheric Sounder (MAS) is a shuttle-based limb-sounding instrument designed for global spectroscopic studies of O3 and constituents important in O3 photochemistry, in the middle atmosphere. It is a part of the NASA?s Atmospheric Laboratory for Applications and Science (ATLAS) spacelab shuttle missions. This paper presents an overview of the instrument, operation, and data analysis. In addition, as an example of the results, we present zonal average retrievals for O3, H2O, and ClO obtained in ATLAS 1. The MAS O3 and H2O measurements are shown to agree well with simultaneous observations made with the UARS MLS instrument
