EMWIN Service Transition - Internet Feed to be Discontinued

I attended the EMWIN Service Transition meeting yesterday.  The meeting discussed the transition to GOES R in 2017.  GOES R combines EMWIN and LRIT into one signal called HRIT/EMWIN. 

They announced that satellite users would need a new receiver.  I have not discussed this with the current EMWIN satellite vendors to see what they are planning.  At this point, it is clear that users of GOES R will need to plan on some sort of upgrade.  It is unknown at this time whether GOES R will replace GOES West or GOES East.

The disappointing news is the loss of the EMWIN Internet feed.  The EMWIN Internet feed is scheduled to be terminated at the end of December 2016.  All EMWIN Internet users will need to migrate to Weather Wire to continue to receive NWS products over the Internet.

As discussed on the conference call, the EMWIN Internet feed contains some international products along with graphics.  These are not transmitted over Weather Wire.  There are technical reasons that they cannot be transmitted using the Weather Wire XMPP protocol.

They announced that the EMWIN FTP service will return to anonymous access in December 2016.  Presently users have to request a user name and password, and supply the NWS with their IP address.

I am sorry to see the loss of the EMWIN Internet feed.  It has served the EMWIN community well for a long period of time.

I will post more information after the next transition meeting.
