Lightning strikes

Lightning strikes in Norway and Sweden from 2001 to the present, recorded by the Nordic lightning detection network. The dataset has two parts. The first is lightning density: the number of cloud-to-ground flashes per km² per year, averaged over all full years. The second is every individual strike, with time, position and current. Source: Meteorologisk institutt (MET). Part of Placepoint's map layer for Risk.

How the dataset is shown in the map​

The dataset is part of the Risk map layer. The screenshot, sub-layers and what a click in the map shows are described under Lightning strikes.

What the numbers mean​

Lightning density is the figure that risk assessments under NEK IEC 62305 use. It is calculated per 1 km grid cell. A single flash often consists of several strikes, so the number of strikes in the map is higher than the number of flashes in the density. Cloud lightning that does not strike the ground is excluded from both.

The lightning detection network also covers the sea and neighbouring countries, so you will see strikes over fjords and along the coast. Density is shown only for land in Norway and Sweden.

Update frequency: Daily.
