A number of ozonesonde stations are operating in the tropics, subtropics, and the southern hemisphere in general, but with differing frequency and reporting procedures. SHADOZ (Southern Hemisphere ADditional OZonesondes) is designed to remedy this data discrepancy, by coordinating launches, supplying additional sondes in some cases, and by providing a central archive location. Since 1998, ozonesonde data have been collected and made available through this website.

Click on the ARCHIVE link in the banner above too access the ozonesonde data.

Questions regarding sonde data from specific stations should be directed to the stations' principal investigator. A list of PI contact information can be found on the CONTACTS link in the banner above.

We would like to keep a running list of papers that use SHADOZ data. Please email a reference of your manuscript to the archiver: Jacquelyn Witte
