Subject: 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 60W 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:


EMWIN is a low cost satellite weather data broadcast service that

provides one of the most resilient methods of receiving NWS

weather information. The service includes warnings, forecasts,

graphics and imagery. The goal of EMWIN is to provide emergency

managers the capability to respond faster to severe weather,

tsunamis and other hazards.
