THE NEW NOAA WEATHER WIRE SERVICE BECAME OPERATIONAL ON JUNE 22, 2000
The Contract for the replacement NWWS was awarded
to DynCorp on September 30, 1999. All WFO/RFC hubs and selected National
Centers will be receiving the new NWWS. The purpose of this Web site is
to keep NWS regional and field offices apprised of the latest developments
in the implementation of the system so as to facilitate the transition
from the old to the new Weather Wire. In addition, information to
help commercial end users as well as State-designated emergency management
agencies transition to the new NWWS is included.

For more information, contact DynCorp at
(800) 633-2340. Information is also available on their website: http://www.weatherwire.net.
They are offering three options for receiving WeatherWire products:
C-band, Ku-band, or Internet service. If you want service closest
to what you currently have on the NWWS, then the C-band option is most
appropriate. The benefits and costs of each option are explained
on the Web site. In addition to a straight purchase, DynCorp is
also offering long term financing plans.
(1) EMWIN (Emergency Managers Weather Information Network) systems are available from many private industry suppliers, and they are listed on the National Weather Service EMWIN Web site. These systems offer an economical way to receive all products available on the NWWS. Compared to the NWWS, typically, an additional broadcast delay of 5 to 20 seconds can be expected for watches and warnings , as compared to the NWWS delay described above. The EMWIN system is monitored on a 24 hour per day, 7 day a week basis, and has an estimated availability of at least 0.99. Being a satellite system, there are short outages of several minutes duration (60 minutes worst case) during a 3-4 day satellite eclipse period which occurs in the spring and fall. The NWWS has backup provisions for such occurrences, whereast EMWIN does not. A backup facility, such as the Internet, might be considered during such scheduled outages. For more information, contact Mr. Ken Bashford at (301) 713-0386 ext. 102, or email@example.com.
(2) The Interactive Weather Information Network (IWIN) can be accessed for free over any Internet connection. This site is maintained by the National Weather Service, and of course is subject to availability of the Internet network. The contact person is the same as for EMWIN, above.
(3) The National Weather Service's Family of Services Public Product Service (PPS) disseminated all public watches, warnings, and other meteorological products which are found in the NWWS data stream. These service is accessible, for an annual fee, directly from the National Weather Service via dedicated telecommunications lines in the Washington, D.C. area, or from commercial providers. For more information, contact Ms. Julie Hayes at (301) 713-1741 ext. 205, or firstname.lastname@example.org.
(4) NOAAPORT satellite broadcast receivers are available for lease or purchase. The NOAAPORT Web site includes a technical description of the system, sample products, and list of equipment manufacturers. For more information, contact Ms. Julie Hayes at (301) 713-1741 ext. 205 or email@example.com.
(5) Private sector weather service
companies and meteoroligists also provide services. The NWS Industrial
Meteorology Web site provides links to these providor home pages as
well as a directory of private weather services organized by State.
For more information, contact the IM staff at (301) 713-0258.

Installation Status is summarized below. Sites indicated as "COMPLETE" may still need to have a USSI technician visit the site to confirm two way operation with the latest software version. All sites will have to go through formal Site Acceptance Testing, which will take place after completion of the System Integration Test, which is currently on Hold pending finalization of the software. IF ANY OF THE INFORMATION BELOW IS INCORRECT, PLEASE NOTIFY THE OSO POINT OF CONTACT.

Site surveys will be posted here as they become available.
4.3 Transition Information
4.3.1 Information Packet
to access the following document, formatted in WordPerfect: NOAA
Weather Wire Service (NWWS) Transition Information Packet.
This is the most current listing of PIL headers and associated product name identification.
This very important document defines the message formats that the NWWS 2000 "Calypso" DCE expects to see from AWIPS and AFOS, and also the message format that end users will see from the broadcast downlink. If there are any questions or concerns, please let us know.
Refer to this link for information on the format conversion tool, which can be very helpful in implementing message header changes from your existing system.
DynCorp has advised that the de-ice system will work from a prime power source anywhere in the range of 198 VAC (4.7 amps) to 242 VAC (3.9 amps), single phase.
All designated State Agencies with an MOU with the NWS, plus all NWS sites, will be receiving software called SKYTAP, produced by Marta Corporation. Any other customer can buy this software directly from the manufacturer. The components are FOSRX (weatherwire data receiver), Router (background data processing), and SAND (weatherwire viewer). This versatile software presents a user friendly interface for selection of products which a site wishes to receive, without the requirement to notify DynCorp, as is required in the present system. Another feature is the ability to select any installed printers(up to four) to print the data output. In addition, warning alarms, archiving, and the ability to re-transmit data are available for computers operating on Windows NT. A description of this softare can be found here. The minimum and recommended computer requirements are as follows:
Minimum System Requirements
Windows-NT - 233Mhz Processor, 64Mb RAM, 1Gb Hard Drive
Windows-95 - 133Mhz Processor, 32Mb RAM, 1Gb Hard Drive
Windows-98 - 133Mhz Processor, 32Mb RAM, 1Gb Hard Drive
Recommended System Requirements
Windows-NT - 450Mhz Processor, 128Mb RAM, 2Gb Hard Drive
Windows-98 - 450Mhz Processor, 128Mb RAM, 2Gb Hard Drive
Please note that for full funcionality, a computer equipped with Windows
NT is strongly recommended. Specifically it must be running NTFS
with Service Pack 5 or
