What Is GLM?
A lightning camera on GOES satellites that watches for flashes day and night across the Americas and nearby oceans. In technical terms: The Geostationary Lightning Mapper, a near-infrared (777.4 nm oxygen line) optical transient detector on GOES-R series satellites with about 8-14 km resolution and 2 ms frame rate, detecting total lightning (intracloud and cloud-to-ground).
Also called: Geostationary Lightning Mapper
