APRSWXNET (Automatic Position Reporting System as a WX NETwork) is a group of ham radio operators and other private citizens around the world that have volunteered the use of their weather data for education, research and use by interested parties. The APRS infrastructure collects the weather data transmitted from individual weather stations and communicates these data to a server. The server then organizes the incoming data stream and makes the weather data available to the Forecast Systems Laboratory (FSL) at 15-minute intervals. This is all done in the public service tradition of amateur radio.
