English: GOES-16 Geostationary Lightning Mapper (GLM) lightning data accumulated over one hour, during which GLM acquired 1.8 million images of the Earth, is displayed over Advanced Baseline Imager (ABI) full disk Band 2 imagery on the afternoon of February 14, 2017. Brighter colors indicate more lightning energy was recorded; color bar units are the calculated kilowatt-hours of total optical emissions from lightning. The brightest storm system is located over the Gulf Coast of Texas, the same storm system in the accompanying video. GLM is able to detect lightning equally well over the entire full disk, including oceans and sparsely populated areas. Coverage of the oceans enables more timely and reliable severe weather forecasts for aircraft traveling oceanic routes where no weather radar coverage is available and for maritime shipping across the entire Western Hemisphere.
