  1. World leader in detection of lightning from space Teams at UAHuntsville have played a leading role in developing: Optical Transient Detector (OTD) (1995-present) Lightning Imaging Sensor (LIS) (1997-present) Geostationary Lightning Mapper (GLM) (2015 launch) LIS’s total lightning data has been used to verify the frequency of lightning is related to microphysical (e.g., ice mass) and kinematic properties (e.g., updraft speed). It has also been used to demonstrate that no appreciable change in global lightning activity has occurred from 1997-present. flashes/km2/year

  2. LIS Characteristics • CCD event detector • 777.4 nm wavelength • 2 ms frame rate • Spatial resolution • 4 km (nadir) – 7 km (edge of FOV) • ~90% flash detection (both intracloud lightning and cloud to ground lightning) GLM’s total lightning data will have immediate applications to aviation weather services, climatological studies, and severe thunderstorm forecasts and warnings.
