“EMWIN is a suite of data access methods which make available a live stream of weather and other critical emergency information.” http://www.nws.noaa.gov/emwin/
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.
