Community Sharing

To find archived data, Unidata community members can use the needdata mailing list. This list is used to request missing or retrospective data. In the spirit of community that has made Unidata a success, subscribers help each other by supplying data that they have available (note that you must be subscribed to the list to post a request). Please be reasonable in your requests; don't expect someone to dig out six months of radiosonde data from 20 years ago.
