Validation of the Stratospheric Aerosol and Gas Experiment-III (SAGE-III)Ozone and Aerosol Data Products
Abstract
The third generation of the Stratospheric Aerosol and Gas Experiment (SAGE-III) was launched in February 2017 and subsequently docked with the International Space Station (ISS). SAGE-III performs solar and lunar occultation observations as the ISS experiences sunrise/moonrise and sunset/moonset events. SAGE-III products include ozone number density and aerosol extinction at nine channels (384, 448, 520, 601, 755, 870, 1020, 1555 nm) with vertical resolution of 0.5 km (0-40 km), and nominal baseline of 5% uncertainty. Evaluation of the ozone and aerosol products has been carried out by intercomparison with a variety of techniques (e.g. ozone sondes, lidar, and occultation) from a variety of platforms (e.g. ground-based, balloon-borne, satellite). Further, data collected under SAGE-III/METEOR (2002-2005) was used to define overpass matching criteria. Preliminary results of the SAGE-III/ISS aerosol product validation are presented herein in addition to a brief discussion of overpass matching criteria.
