The Mission
The National Weather Service (NWS) provides weather, hydrologic, and climate forecasts and warnings for the United States, its territories, adjacent waters, and ocean areas for the protection of life and property and the enhancement of the national economy. NWS data and products form a national information data base and infrastructure which can be used by other governmental agencies, the private sector, the public, and the global community.

Issues
• Data Explosion– Increased resolution of observations and models– Increased frequency of observations and models– Increased number of sensors– Improved sensing technology– New spatial and temporal requirements– Graphics, imagery, and video– Thousands of small products
• Bandwidth– Technology selection– Estimation of capacity growth– Transmission of ‘information’ versus ‘raw data’
