The definition of and relationship among flashes, groups, and events are governed by the following spatial and temporal characteristics: An event represents the signal detected from the cloud top associated with a lightning emission in an individual sensor pixel for a 2ms integration period; A group represents the events detected in adjacent sensor pixels for the same integration period as an event; A flash represents a series of measurements constrained by temporal and spatial extent thresholds that are associated with one or more groups. The parent, child relationship among specific flashes, groups, and events is stored in the product. Data for each flash includes an energy-weighted centroid latitude, longitude location, time span of occurrence, amount of radiant energy, and coverage area. Data for each group includes an energy-weighted centroid latitude, longitude location, mean time of occurrence, amount of radiant energy, and coverage area. Data for each event includes a latitude, longitude location, time of occurrence, and amount of radiant energy. The product includes data quality information for each flash and group. A Lightning Detection product file contains a set of flashes, and its constituent groups and events for a 20 second period. The units of measure for the flash, group, and event radiant energy values is Joules. The units of measure for the flash and group coverage areas is square meters. Currently weather forecasters can use lightning data provided by a surface-based network to help "nowcast" severe weather. This is a valuable tool; however, it only has the capability of detecting cloud-to-ground flashes. The GOES-R satellites will have the capability to detect both cloud-to-ground and inter-cloud lightning, through use of the Geostationary Lightning Mapper (GLM). This will help severe weather forecasters identify thunderstorms which are rapidly intensifying, and enable them to issue accurate and timely severe thunderstorm and tornado warnings.
