AB: Occultation data has been instrumental in increasing our understanding of global dynamical and chemical processes of the atmosphere. The use of occultation data in the upper stratosphere and lower mesosphere has been key to understanding the coupling between these regions (e.g., high latitude, winter/spring, NOx transport from the mesosphere into the upper stratosphere). Occultation data has been fundamental in understanding the processes that control stratospheric ozone and water vapor distributions and trends. And recently, occultation data has been used to better characterize the chemical and dynamical properties of the upper troposphere / lower stratosphere (UTLS) region. This presentation will focus on how occultation data, specifically that from SAGE II, HALOE, POAM II, POAM III, ILAS, and ILAS II, has been used in the above-mentioned regions to evaluate 3D chemical transport models and more recently 3D chemistry climate models. Specific scientific studies using these models with occultation data will be shown. Needs for development of future occultation platforms will be highlighted.
