The Earth Networks Total Lightning Network was the first lightning network to accurately measure and classify both in-cloud and cloud-to-ground lightning. In the past, most lightning detection networks only focused on cloud-to-ground strikes. That’s why we say it’s a “total” lightning network.

Cloud-to-ground lightning is just what it sounds like: a bolt of lightning shoots between a storm cloud and the earth. This is what most of us think about when we think of “lightning.” In-cloud lightning refers to the electrical activity that happens high above our heads within the storm but never makes it to ground. Typically, storms that produce cloud-to-ground strikes have even more activity occurring within the storm system.

In-cloud lightning is an indicator of danger for cloud-to-ground strikes in areas where those strikes might not be occurring yet. That means that if you only monitor cloud-to-ground strikes, you’re taking a reactive approach to lightning safety rather than a proactive one.

ENTLN data can be visualized using the AEM Elements™ 360 multi-hazard decision support application or Sferic Maps.
You can set alerts and notifications around proximity thresholds for a specific location directly in Elements 360 or Sferic Maps. You can receive those alerts directly via the application, email, or text.

Yes! The Sferic Siren outdoor warning system provides an audible horn and visible strobe light uses data from the ENTLN. When lightning approaches your area, the alarms trigger automatically to tell everybody to seek shelter or initiate your weather emergency protocol. More discrete indoor alerting systems are also available.

Yes! Our Lightning API allows you to choose from a wide range of flexible options to get direct access to historical or live total lightning data to fuel your own weather apps, predictive models, and analytics in the way that works best for your organization.
