2 July 2014 Last updated at 09:39 BST
A world-wide team of volunteers is helping to create a low budget, lightning location network using a low frequency radio receiver.
The last two hours of lightning activity is displayed on the Blitzortung website and can be used by weather hobbyists and not-for-profit meteorologists for use in their predictions and weather forecasts.
