The Largest Lightning Sensor Network
ENTLN has expanded to include more than 800 sensors in more than 40 countries around the world, including North and South America, the Caribbean, Europe, Australia, Africa and Asia. ENTLN commands the dense sensor deployment needed to achieve high efficiency capture of total lightning activity. ENTLN data is currently being used by a variety of government agencies and commercial enterprises.
ENTLN: Unique Lightning Detection Characteristics
Detection of cloud-to-ground (CG) lightning is critical in protecting people and property. However, CG lightning actually accounts for only a small percentage of the total lightning discharges that occur in the atmosphere. In-cloud (IC) lightning flashes, on the other hand, account for the vast majority of lightning activity. High detection efficiency of IC for discharges, combined with advanced analytics and display capabilities, enable improved lead times for identification of storm cell growth and development to improve early storm warning capability.
Total Lightning Detection and Severe Weather Alerting
The network's ability to detect both in-cloud and cloud-to-ground flash signals at high efficiencies makes it practical to track and predict severe weather in real time. By using the total lightning data and a real-time lightning cell tracking system, the Earth Networks Dangerous Thunderstorm Alert (DTA) system has been developed. A DTA is issued when the ENTLN detects a high frequency of lightning, which indicates the increased potential for:
The Dangerous Thunderstorm Alert appears as a purple alert area polygon accompanied by an associated text alert. The DTA can be used to enhance weather monitoring systems operated by national meteorological associations, or may be utilized in areas where meteorological tools such as radar are unavailable -- serving as a vital missing link that can help save lives and protect property. Earth Networks provides total lightning data via standard application program interfaces (APIs), desktop visualization tools such as StreamerRT, and Google Earth.

Worldwide Lightning Detection Providing Advanced Severe Weather Prediction and Alerting
The Earth Networks Total Lightning NetworkTM (ENTLN) incorporates patent-pending systems and technology to provide unmatched in-cloud and cloud-to-ground lightning detection. It is the first in-cloud (IC) lightning and cloud-to-ground (CG) detection network deployed on a global basis capable of detecting long range in-cloud lightning at high efficiencies critical for the advanced prediction of severe weather phenomena such as:
These potentially deadly weather events often occur within 5 to 30 minutes of in-cloud flash initiation. The ENTLN has demonstrated the ability to significantly improve severe weather warning times over radar and other technologies by incorporating highly advanced predictive capabilities that are crucial for characterizing severe storm precursors, improving severe storm warning lead times, and comprehensive weather management planning. ENTLN data is extremely valuable for meteorological and government agencies, aviation, utilities, sports and recreation, and for mobile alerting.
