NWSTG Functional Overview

  • The NWSTG is

  • the central communication facility of the NWS;

  • the primary acquisition and distribution center for NWS data and products;

  • the primary acquisition and distribution center for international data and products to meet WMO, ICAO and bi-laterally agreed US requirements;

  • A major data exchange hub for NOAA and other agency data and products.

NWSTG Functional Overview

The NWSTG includes

  • WMO Regional Telecommunication Hub (RTH) Washington

  • ICAO OPMET Databank (KWBCYMYX)

  • the ASOS Operations and Monitoring Center (AOMC)

    • Operational oversight of U.S. federal automated surface observing systems

  • the AWIPS Network Control Facility (NCF)

    • AWIPS is the main NWS’ system which supports the NWS forecast and warning mission requirement

    • The NCF is the central communications hub and technical support center for AWIPS

    Government networking requirements

    Government Networking Requirements

    • IP-based networking solution

      • Any-to-any connectivity

      • High degree of bandwidth scalability

      • Optimum redundancy and survivability

      • IP convergence (i.e., voice, video and data over IP)

      • High-end performance

    • Network security remains paramount, particularly in light of today’s socio-political threats

    • Segmentation from the public Internet

      • Minimizes risk of security or privacy breaches
