The Southern Hemisphere Additional Ozonesondes (SHADOZ) is a project to augment balloonborne ozonesonde launches, and to archive data from tropical and subtropical operational sites. The project was initiated in 1998 by the NASA/Goddard Space Flight Center, with NOAA and international co-investigators in Europe, South America, Asia, and Africa. There are currently thirteen operational stations in the Network. The collective data set provides the first profile climatology of tropical ozone in the equatorial region, enhances validation studies aimed at improving satellite remote sensing techniques for tropical ozone estimations, and serves as an educational tool for students, especially in the participating countries. As a flexible archive, SHADOZ has grown and evolved as scientific needs and research questions change. In addition to the NDACC link, SHADOZ data are transmitted regularly to the WOUDC , and are archived in HDF for the satellite user community at the Aura Validation Data Center.
Data are collected and available publicly at the SHADOZ official website. The Principal Investigator of SHADOZ is Anne Thompson of NASA’s Goddard Space Flight Center. The Archiver and Webmaster is Jacquie Witte, also at NASA/Goddard. Station locations, CoInvestigator contacts, and technical details of the operations are also archived at the website.
