GOES-R Lightning Mapper animation Transcript 0:53 0:00 Lightning is more than nature's fireworks display. Research has shown 0:05 that lightning is an excellent early warning indicator for approaching severe 0:08 storms and the development of tornadoes.This data visualization shows actual 0:13 lightning measurements captured by a remarkable array of ground-based 0:16 lightning detectors capable of tracing how lightning propagates through the 0:20 atmosphere. 0:22 From space, the intersection of lightning and its corresponding cloud fronts 0:26 becomes clear. That's why on the nation's new environmental satellite, 0:30 called GOES-R, an advanced lightning mapper known as GLM and will survey 0:35 much of the Western Hemisphere for atmospheric flashes. According to GOES-R 0:39 scientists this technology could help provide critical minutes of 0:43 valuable warning time in advance of approaching severe storms.
