The Unidata Program is not responsible for the use of the data it provides. However, all users agree to comply with the Unidata Pariticipation and the Data Policy. Additionally, there are some restrictions on the usage of data (see International Data and Products with Controlled Access-WMO Resolution 40) acquired through the Unidata Program. The general guideline covering all types of data is data are provided solely for education and research purposes. That is based on the following:
Specific guidelines apply to particular data streams, and some of these require agreements between each user organization and the provider of the data.
Data acquired from the Unidata-Wisconsin datastream or NOAAPORT via the NWS Telecommunication Gateway are free and openly available for data exchange, with the exception of the international datasets affected by WMO Resolution 40.
There are many data streams made available for use with Unidata systems.
Unidata governing committees discuss potential data streams of interest on behalf of the community and the Unidata Program researches the feasibility of provision of the data sets. Community members may offer particular data sets to other participants or use Unidata tools to provide data to their collaborators.
The Unidata Program requests an acknowledgement (in publications, conference papers, etc) from those who use data received with Unidata systems, and tools and software. Such an acknowlegement is highly valuable to support continued funding for the Unidata Program. In case of proprietary data, data providers may require additional attribution of data acquired from them.
*Note: Due to Internet Data Distribution system, commercial level of reliability is not guaranteed. Those needing data for operational or decision-making purposes should acquire them directly from the private vendors.
