摘要:The Unified National Space Weather Capability (UNSWC) Memorandum of Understanding (MOU) and Annex have been approved by the National Space Weather Program (NSWP) Council {www.nswp.gov}. The UNSWC is the product of interagency coordination and collaboration among all the NSWP partners. All nine NSWP partner agencies contribute to the UNSWC in various ways; however, five of the agencies (US Air Force, the National Oceanic and Atmospheric Administration, the National Aeronautics and Space Administration, the National Science Foundation, and the US Geological Survey) wanted a stronger foundation for participating and providing resources for interagency initiatives. The other NSWP partners not covered by the UNSWC MOU participate in the utilization, application, and coordination of the UNSWC without the need for additional justifica- tion and authority to do so. Additionally, the UNSWC serves as the internationally recognized entry point to US space weather support and services, encompassing the ongoing contributions of all ofthe NSWPmember agencies.
