Summary
The Ascension Island Observatory 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.
