Abstract
A global network of seven time‐synchronized, high‐precision magnetometers around the world is ready to triangulate individual lightning flashes on planet Earth to monitor the temporal and spatial evolution of global lightning activity.
This global network of magnetometers is able to detect the electromagnetic radiation of distant lightning flashes and makes possible remote sensing of the temporal evolution and spatial migration of global lightning activity [Füllekrug and Constable, 2000]. These results have led to international interest in a new measurement campaign with a large network of high‐precision magnetometers. The magnetic field changes are measured with ∼10‐14 Tesla accuracy (which corresponds to ∼10‐7% of the main geomagnetic field). The Global Positioning Satellites (GPS) provide time alignment of 0.00002 seconds between two measurement stations at antipodal distances (20×103, km), and the digital equipment makes possible continuous, high‐frequency recordings with 2000 samples per second.
