1 00:00:01,710 --> 00:00:06,100 Lightning is more than nature's fireworks display. 2 00:00:06,120 --> 00:00:11,170 Research has shown that lightning is an excellent early warning indicator 3 00:00:11,190 --> 00:00:12,910 for approaching severe storms. 4 00:00:12,930 --> 00:00:19,230 This data visualization shows actual lightning measurements captured from a remarkable array of ground based lightning detectors 5 00:00:19,250 --> 00:00:23,390 capable of tracing how lightning propagates through the atmosphere. 6 00:00:23,410 --> 00:00:32,270 From space the intersection of lightning and its corresponding cloud fronts becomes clear. 7 00:00:32,290 --> 00:00:35,070 That's why on the nation's new weather satellite called GOES-R 8 00:00:35,090 --> 00:00:45,750 an advanced lightning detector system called GLM 9 00:00:45,770 --> 00:00:50,240 will begin surveying the entire nation for atmospheric flashes. 10 00:00:50,260 --> 00:00:51,210 according to project maagers this technology could provide valuable minutes of critical warning time 11 00:00:51,230 --> 00:00:57,879 in advance of approaching storms.
