This is a new way to think about global lightning

WSI (Weather Services International), the leader in weather-driven business solutions, today announced the introduction of the Global Lightning Network (GLN), a source of high quality real-time lightning detection data for clients throughout the world. The Global Lightning Network is comprised of advanced lightning stroke detection sensors strategically located at international hosting partner sites. Data from the GLN has the timeliness, coverage, and delivery to support critical business operational requirements in key areas, without compromising quality, accuracy, and efficiency. Real-time data from the network is provided seamlessly via the Internet in less than a minute of event detection. The current key deployment areas include North and South America, Southeast Asia/Australia, and Europe, including many areas where lightning has significant economic and safety consequences. Data is also available for oceanic and other continental regions.

The Global Lightning Network uses the same lightning sensor and processing technology that has been proven in the United States Precision Lightning Network (USPLN). Like the USPLN, the GLN is a partnership of WSI and TOA Systems, a preeminent manufacturer of integrated lightning location and detection systems. "This is a new way to think about global lightning," said Mark Gildersleeve, President of WSI. "WSI and TOA are the first to bring to market a commercial global lightning network addressing the diverse needs of consumer, business, and government clients. Our mission is to create the highest quality unique weather content for the entire globe, and lightning is a key component of this strategy."

Kim Rauenzahn, WSI's Lightning Product Manager, noted, "While lighting has significant value as a supplement to radar for identifying and evaluating convective activity, it is an essential source of information where radar is not available. There are many instances where disruptive weather events put people and property at risk, and additional weather coverage can be vital to improving the outcome of these events. For example, our airline clients with global routes have been asking for enhanced weather information to enable better decision making both en route and on the ground. Data and services from the Global Lightning Network are a major component of the solutions meeting these weather information needs."
