International Data and Products
with Controlled Access

A number of countries distribute a small set of data and products with conditions. The data and products are listed by WMO abbreviated heading. This web site lists only the WMO meteorological bulletins expected at the NWS Gateway from international sources.

The U.S. agreed during the XIIth World Meteorological Congress (June 1995) it would make its best effort to inform subsequent recipients of foreign data, exchanged over the World Weather Watch system, about conditions placed on "additional" meteorological and related data and products, according to WMO Resolution 40. Since the adoption of WMO Resolution 40, the U.S. private sector and research and education communities have had full access to all real-time data and products via the NOAA Family of Services dissemination system, and all delayed data and products via Anonymous FTP (file transfer protocol) over the Internet. To date, we are not aware of any violations by the U.S. meteorological community.

The U.S. recently reviewed its policy on Internet distribution of foreign data and products. It was determined, according to the letter and spirit of WMO Resolution 40, "additional" data and products would be distributed over the Internet. As agreed, notification of the conditions on the "additional" data and products will be provided during distribution.
