Geostationary Lightning Mapper Image Gallery

The GOES-R Series Geostationary Lightning Mapper (GLM) is the first operational lightning mapper flown in geostationary orbit. GLM, an optical transient detector and imager, detects and maps total lightning activity over the Americas and adjacent ocean regions. GLM collects information such as the frequency, location, and extent of lightning discharges to identify intensifying thunderstorms and tropical cyclones.
