Changes to NWS Information Services

This site provides information on changes under consideration by NWS to information services that provide environmental information to NWS users.

The nation benefits from government information disseminated both by Federal agencies and by diverse nonfederal parties, including commercial and not-for-profit entities. NWS recognizes cooperation, not competition, with private sector and academic and research entities best serves the public interest and best meets the varied needs of specific individuals, organizations, and economic entities. NWS will take advantage of existing capabilities and services of commercial and academic sectors to support efficient performance of NWS's mission and avoid duplication and competition in areas not related to the NWS mission. NWS will give due consideration to these abilities and consider the effects of its decisions on the activities of these entities, in accordance with its responsibilities as an agency of the U.S. Government, to serve the public interest and advance the nation's environmental information enterprise as a whole.
