Subject:  New NOAA Weather Wire Service During 2012


A new NOAA Weather Wire Service (NWWS) will be commissioned during 2012. The new NWWS will operate concurrently with the current NWWS system for a period of time before the old NWWS system is decommissioned (turned off) in March 2012 at the earliest. For the latest news and information about this change, please consult the Weather Wire website at:


This website will be updated as needed to keep you informed. Also, see page 6 of the summer Aware report, available at


With the new system, C-band satellite users can continue to
re-use the outdoor antennas they already have in place (which will not require re-pointing), but will need a new satellite receiver, new Low Noise Block Converter (LNB), and new (or modified) weather data display software.   Internet (Open Interface) users will need the new (or modified) display software.

Operational requirements for system reliability and data timeliness for the new NWWS remain the same as the current NWWS. Costs will be at or below current costs.  We will have more specific information about the satellite receiver, LNB, and software you will need after we have completed our testing on this equipment later this summer.

The old NWWS system (operated under contract with Computer Sciences Corporation (CSC) for the past 12 years) will continue to operate into 2012, and will not be decommissioned (turned off) until March 2012 at the earliest.
