External USB Sound Card for the Werner Labs Receiver

The Behringer UCA202 Audio Interface can be used with the Werner Labs Receiver.  This is an external USB Sound Card.  It eliminates the need to use the internal sound card for processing the receiver's data stream.


One of my customers is using this interface with a virtual machine.

New Weather Wire Feed Confirmed

The NOVRA S300N receiver settings, for Weather Wire, in the previous blog post have been confirmed.  I was able to receive data from the new Weather Wire feed tonight.

I made some modifications to WxPort (our NOAA Port ingest program) to receive the data stream.  The stream is in standard SBN format, so I did not have to develop a new ingest routine.

The following picture shows the stream being received and processed by Weather Message.

I plan to update the existing WxWW2000 ingest program to support this feed.

Novra Receiver Settings

I have been trying to receive the new WeatherWire stream using my Novra S300 receiver.  I thought it was as simple as adding PID 201 to the Novra receiver.  After further research I found that some of the other receiver settings would have to be modified.

The following summarizes the settings for Weather Wire and NOAA Port.

NOAA Port 
Weather Wire 
 2/3 8 PSK
 1/3 QPSK
 Symbol Rate

Based on this information, it does not appear that you can receive NOAAPort and WeatherWire from the same receiver at the same time.

New Weather Wire Service Coming this Fall

The National Weather Service issued a Service Change Notice that outlines the new Weather Wire Service.  It appears that Weather Wire will be on the same satellite as NOAAPort.  It will use the same receiver as NOAAPort and share the transponder.  The information that has been posted indicates that it will use PID 201.

Here is a picture of the Novra S300 receiver used for NOAAPort.

I am interested to see what data will be on the Weather Wire channel.  The NOAAPort stream already contains more data than the current Weather Wire feed.  The website indicates that they will be providing an internet feed based on XMPP.

It may be possible to modify the WxPort (NOAAPort) ingest engine to receive the data from the satellite.  I will know more after seeing the data stream.  The WW2000 (Weather Wire) ingest will have to be rewritten to receive the XMPP data stream.

Subject:   New NOAA Weather Wire Service (NWWS) During 2014   
NWS is continuing the upgrade of NWWS to disseminate weather products to the public. A new NWWS will be commissioned during 2014. The new NWWS will operate concurrently with the present NWWS system until the NWWS system contract ends March 2014, at the earliest. For the latest news and information about this change, please consult the Weather Wire website at: 
    http://www.nws.noaa.gov/nwws/news.html  (Corrected Link)  
The new system will allow C-band satellite users to continue to use outdoor antennas they have in place, which will not require re-pointing but will require a new satellite receiver, new Low Noise Block Converter (LNB), and new or modified weather data processing/display software. Internet (Open Interface) users will need the new or modified processing/display software.   
The current NWWS system, operated under contract with Computer Sciences Corporation (CSC), will continue to operate into 2014.  CSC may or may not continue Weather Wire satellite and open-interface services after government contract termination.   
Updates will be posted on the NWWS website as it become available. For more information please contact:

Radar Layer in WxMap

I had some time tonight to test loading a radar layer in WxMap.  I knew that the GIS engine would support graphic layers, I just have not had time to test the capability.

Here is a snapshot of the test program.


This shows the KMXX radar image overlaying West Alabama.

GOES 12 Decommissioning to Occur August 16, 2013

GOES-12 is scheduled to be decommissioned on August 16, 2013.

GOES-12 was launched on July 23, 2001, and it has supported South America at 600W since May 2010. The National Environmental Satellite, Data, and Information Service (NESDIS) announced the decommissioning on July 9, 2013.

The decommissioning will end the broadcast of the EMWIN-I legacy data stream.  This broadcast was put in place to assist users in the transition to EMWIN-N on the operational GOES East and West satellites and facilitate manufacturer testing. Any remaining legacy users should migrate to EMWIN-N capable systems and use GOES East or West.

GOES 12 EMWIN-I users can also continue to receive EMWIN with an Internet connection through the EMWIN ByteBlaster Network if unable to upgrade to newer equipment.

For the latest information on the GOES 12 decommissioning and for a list of vendors that currently provide EMWIN-N capable systems, please go to:

GOES 13 is Broadcasting EMWIN Data

GOES 13 is now broadcasting EMWIN data.  Here is the latest update.
GOES-13, at 75 degrees West, will return to GOES-East operations on Thursday, June 6, 2013, at approximately 1534 -1545 UTC (first image at 1545 UTC). Derived products from GOES-13 will begin immediately following the switchover.

All GOES direct readout services (DCS, LRIT, EMWIN, etc.) except SAR were switched over to GOES-13 today, June 4, 2013. Specifically, GOES DCS services were switched back to GOES-13 on June 4, 2013, at 1530 UTC.

GOES DCS has no issues and there has been no outage to the communications packages.

GOES 13 Status

I know many of you are trying to decide whether to reposition your dish to GOES-14. Here is the latest status on GOES-13. 
GOES-13 remains out of service with no estimate on return to operations at this time. It was successfully brought out of storage mode for testing last night, and will be monitored for 24 hours.
It appears that there is still some life in GOES-13.  Hopefully it can be brought back on-line.

GOES 14 takes over for GOES 13

From the EMWIN Team:
GOES-14 at 105 degrees W now broadcasting EMWIN

EMWIN Users:

To help mitigate the GOES-13 outage, GOES-14 is now broadcasting EMWIN data. It is located at 105 degrees West.

GOES-14 It will not be drifted east. Engineering at NESDIS will continue to investigate the anomaly. Meanwhile, GOES-13 will remain in storage mode.

Users now have the option to re-point to GOES-14 or remain in back up mode with antennas still pointed at GOES-13.

EMWIN team

GOES 13 Outage

From the EMWIN Team:

Be advised that there is an anomaly on the GOES 13 satellite that affects systems on the spacecraft including the EMWIN broadcast. NESDIS engineering is working on the problem. Please switch to the Byteblaster back up or point your antenna to GOES 14.

EMWIN team

You will find details on the problem on this web page.

EMWIN Logon Changes Tested

I participated in the EMWIN Logon changes test this week.  Starting June 10, 2013, the National Weather Service will require all EMWIN FTP users to use an assigned user name and password to access the FTP server.  If you do not use the FTP method to access the server, no changes are required.

If you use the EMWIN FTP server, you should send an email to Rob Wagner,  EMWIN Team,  Office of Operational Systems, robert.wagner@noaa.gov with your static or dynamic IP address.  You will be assigned a user name and password to access the FTP server.

In a previous blog post I announced that users would be required to use a static IP address.  The NWS will now filter dynamic IP users on the first three octets of their IP address.  This should not be a problem for most dynamic IP users.  (The first three octets are highlighted in the following IP address:

I noticed that my Verizon 4G wireless connection does change that third octet on occasion.  Because of this, I have sent multiple IP addresses for my registration.

Weather Message 4.0 contains changes that allows users to enter their assigned user name and password.

Note: To my knowledge a small number of Weather Message users use the FTP ingest option.

Weather Message 3.9.3 Released

Weather Message version 3.9.3 was released today.  This version of Weather Message contains changes to address problems with authorizing Facebook and Twitter.  If you have already authorized these services, you do not need this update.

These changes have already been included in the current 4.0 beta.

Facebook Changes

Facebook deprecated off-line access in December 2012.  This change causes new Weather Message users to get a short lived access token.  The short lived access token is good for 2 hours.

Changes have been made in Weather Message to extend this initial access token to 60 days.  When the 60 day access token expires, Weather Message users will need to reauthorize the Weather Message application for another 60 days.

It appears that Weather Message users with an original access token, one issued prior to December 2012, do not have this constant reauthorization problem.  New users will have to reauthorize the application routinely.

We are still looking into this problem.  In the mean time, we have released Weather Message version 3.9.2.  The version contains revised code to obtain the 60 day access token.  A beta release for version 4 will be posted soon.

EMWIN News: GOES 12 End-Of-Life

GOES 12 at 60 degrees is nearing end-of-life.  The satellite currently is broadcasting the EMWIN-I legacy data stream.  NESDIS has yet to set an exact date for GOES 12 to be removed from service, but it is expected to occur in the fall of 2013.  Any remaining legacy users should migrate to EMWIN-N capable systems and use GOES East or West.

EMWIN FTP Logon Changes Effective June 10, 2013

The NWS announced today that they will start requiring a user name and password to retrieve files from the EMWIN FTP server. Your user name and password will be associated with your computer's static IP address. In order to download files from the EMWIN FTP server, you will now need a static IP address.

These changes will require an update to Weather Message. I will make an announcement when the changes are completed.

Here is the text from the Public Information Statement.

Effective June 10, 2013, EMWIN FTP users must apply for a username, a password and provide the IP addresses of systems that retrieve files from the EMWIN FTP server. This change DOES NOT affect satellite broadcast or ByteBlaster users.

The IP addresses will be used to obtain access to the server.
Users will need to ensure they use a static IP address, one that remains the same and is not assigned dynamically and therefore changes between user sessions. If users are unsure if they have a static IP address or need to have one established, they should contact their Internet provider.

After June 10, users will be required to use their new username and password to continue to retrieve data from the EMWIN FTP server. It is strongly recommended that users transition to their new username and password as soon possible to avoid loss of service after June 10, 2013.

To apply for a username and password or for other questions,

Rob Wagner
Office of Operational Systems
