EMWIN: Emergency Managers Weather Information Network

1

“EMWIN is a suite of data access methods which make available a live stream of weather and other critical emergency information.” Emergency Managers Weather Information Network

Originally, (20+ years ago) EMWIN ran at 1200 and 9600 bps. EMWIN-N (NexGen, 2009) runs at 19.2kbps.

Primarily broadcast via internet and satellite, there were/are a few local VHF and UHF relays.

Software such as Weather Message, ingests the messages and can activate local alarms when a local watch or warning occurs.

Even at only 19.2kpbs, this service generates a large amount of useful information.

While I enthusiastically support the idea of “Humanity’s Public Library.” I think looking a the system architecture of EMWIN would be very beneficial to Outernet developers. Especially, the idea of activating a local alarm based on local information.

I see a problem with the offering of weather mainly in the amount of data that would be required for global maps. We here in the Americas have the luxury of the 2 Goes satellites we could use .
