(Abstract) EMWIN Satellite Transmission Service

The Emergency Management Weather Information Network (EMWIN) was established approximately 10 years ago to provide near real-time emergency weather information via relatively low-cost L-band receiver systems. The current EMWIN system shares the existing GOES WEFAX L-band transponder to continuously broadcast emergency weather information through the two operational GOES satellites. This presentation provides an overview of the legacy EMWIN system and its transition to the GOES-N digital era.
