Blitzortung

This is another one of these great German words to mess with non-native speakers - go ahead...try pronouncing it correctly! In English: lightning locator and Blitzortung.org is global, real-time, community-based lightning detection network - fun! Check-out LightningMaps.org for a fancier web map. You can get involved yourself and they'll send you everything you need at-cost (not sure how much that is).
