Vaisala's Continuing current Dataset has been developed to identify the small fraction of cloud-to-ground lightning strikes with continuing current; they are the events that can be the most destructive and are most likely to initiate wildfires, put holes in wind turbine blades and damage other electro-mechanical assets.

Counter-intuitively, the majority of these destructive events are not higher peak current events, in fact, quite the contrary. They cause extreme heating, having a duration up to 1000 times longer than the other 90% of strokes, as they transfer significantly more electric charge to whatever they are in contact with.

When your operations get hit by a thousand lightning strikes in a single storm-event, identifying these lightning strikes provides valuable information for preventing further damage.
