Online module
This extension of the COMET module “GOES-R: Benefits of Next Generation Environmental Monitoring” focuses on the Geostationary Lightning Mapper (GLM) instrument, the satellite’s lightning mapper. The GLM will provide continuous lightning measurements over a large portion of the Western Hemisphere, mapping total lightning (intra-cloud and cloud–to–ground) flash rates and trends. GLM observations will improve local forecasts and warnings of severe weather and air quality, and provide new data for numerical weather prediction and studies of regional climate and climate change.
