3. What is NOAAPort? NOAA’s Satellite Broadcast Network NOAAPort– also known as the Satellite Broadcast Network (SBN)– is the primary vehicle through which hydrometeorological products are provided to NWS field office AWIPS systems. The vast majority of NOAAPort products are freely available to NOAA’s partners.

NOAA’s Satellite Broadcast Network GOES POES NOAA/NESDIS NOAA/NWS DCS AVHRR HIRS/AMSU GVAR NCEP Hydromet Sensor Products (e.g., radar, ASOS, Profiler, River Gages) TOC NWSTG Satellite Product Generation AWIPS NCF Guidance & Model Products Satellite imagery Other Environmental Satellite Products SES-1 Satellite NOAAPort Uplink Facility (NY) WFO/RFC Forecasts, Watches Warnings NOAAPort Users Includes Many Users – Inside and Outside of NOAA

5. NOAAPort Approximate Coverage Area

6. NOAAPort Channels - There are four NOAAPort data streams, each with a unique DVB PID: GOES/NESDIS NCEP/NWSTG NCEP/NWSTG2 OCONUS Imagery/Model/DCP Expansion Drivers – Existing NOAAPort channels are highly utilized. Emerging requirements, such as for NPP, GOES-R, JPSS, NCEP model, and dual polarization radar, necessitate network expansion. NOAAPort Channels and Network Expansion

7. NOAAPort Network Expansion Expansion currently underway! Network bandwidth increase from 10 to 30 Mbps. Transition from DVB-S to DVB-S2. Supports MPE and VCM. 30 day window of “dual illumination,” April 18 to May 17, 2011. AWIPS SBN Channel Resizing – New product additions, starting in July-August 2011.
