SETI Live: Tracking Lightning from Space to Predict Weather on Earth

Lightning flashes can be excellent predictors of incoming storms, tornadoes, and other severe weather events and are used by meteorologists to warn local communities of oncoming severe weather many minutes in advance, protecting infrastructure and human lives. NASA’s two Geostationary Operational Environmental Satellite (GOES) spacecraft have cameras dedicated to capturing emitted light on Earth. This camera, known as the Geostationary Lightning Mapper (GLM), captures and records the intensity of light on any camera pixel with a brightness above a certain threshold. These records are considered a single “event” and are downlinked to receivers back on Earth. The Frontier Development Lab's Lightning Upgrade team seeks to achieve a greater classification accuracy of true lightning events by applying machine learning algorithms to GLM data.
