nwstg functional overview
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
