Ozone Data from the American Samoa Observatory, Southern Hemisphere Additional OZonesondes (SHADOZ) Project, NASA

Abstract: The American Samoa Observatory, operated by NOAA CMDL measures ozone data using balloon-borne ozonesondes as part of the NASA Southern Hemisphere ADditional OZonesondes (SHADOZ) project. The SHADOZ project is collecting ozone data for validation, processing, and modeling of satellite-derived Total Ozone Mapping Spectrometer (TOMS) data.
