How does lightning detection work
These two systems work by detecting radio waves (sferics) emitted by fast electric currents (strokes) in lightning channels. A “stroke” can be a fast current within the cloud, or a “return stroke” in a channel to ground. CG return strokes usually have larger currents that make stronger signals that are easier to detect. See more Currently, cloud-to-ground (CG) and intra-cloud (IC) lightning flashes are detected and mapped in real-time by two different networks in the United States--the National Lightning Detection … See more Lightning Mapping Arraysprovide three-dimensional mapping of lightning channel segments near the array. Up to thousands of points can be … See more Flashes have also been detected from space during the past few decades by other optical sensors which preceded the GLM - the Optical Transient Detector and the Lightning Imaging Sensor. The Optical Transient Detection … See more The Geostationary Lightning Mapper (GLM)is an instrument on two weather satellites launched in 2016 and 2024 (GOES-16 and GOES … See more WebA lightning detector is a device that detects lightning produced by thunderstorms. Personal lightning detectors are popular among golfers, campers, law enforcement, sports officials, and other persons who work or recreate outdoors. Personal lightning detectors function by detecting the electromagnetic pulse (EMP) emitted by a lightning strike.
