The Spotter Network is a system that utilizes storm spotter and chaser reports of location and severe weather in a centralized framework for use by coordinators such as emergency managers, Skywarn and related spotter organizations, and the National Weather Service. It uses GPS to provide accurate and automated position data of storm spotters and chasers for coordination and reporting, which in turn provides ground truth to public servants engaged in the protection of life and property. The network is a combination of locally installed software for position and status reporting and web-based processing, mapping, and reporting. The original Spotter Network was developed by Tyler Allison. The current president of the organization is John Wetter. It became operational in April 2006 and quickly grew to over 100 spotters. Several National Weather Service employees and other officials soon took an interest in the capabilities it brings to them to integrate ground truth provided by spotters into their operational responsibilities. Subsequent versions of the network expanded the coordinator and reporting capabilities, and NWS eSpotter integration was completed in early September 2006. Spotters must pass an online test of storm structure and basic meteorology in order to use the system. All reports are also reviewed for quality control purposes. Contact information is provided by users and can be controlled to reach the all users or selectively to reach emergency managers and NWS officials. SN features GIS capabilities for use with external websites and apps. Several papers have been written on the use of the Spotter Network in meteorological research and operations such as:
The SN is officially a Minnesotanon-profit corporation, and is recognized as a 501 organization by the IRS and is run as an organization of like-minded individuals taking input from the various communities that it serves and making the output available to any and all who are interested in severe weather. The SN has a Board of Directors and an advisory committee made up professional meteorologists, storm spotters, storm chasers, emergency response personnel, and NWS officials. On February 26th, 2017 storm chasers paid respects to 'Twister' star Bill Paxton by arranging their position indicators to form the initials BP.
