Lightning Detection and Meteorological Applications from Ground and Space

Study by Dr Eric Bruning, Department of Geosciences, Texas Tech University.

Modern lightning measurements are now well advanced beyond point detection of ground strikes, and reveal the extent of flashes within the cloud. These measurements of flash rate and flash size are tied to the electrostatic energy dissipated by each flash, though it remains difficult to predict the precise amount of that energy emitted as optical light.

Understanding lightning phenomenology, as detected by a suite of RF and optical instruments, is important for the design and validation of optical, space-based lighting measurements (GOES-R GLM, MTG LI and the heritage LIS measurements), as well as their application in meteorological forecast and nowcast settings.

This presentation provides a short overview of storm electricity basics, lightning, and its detection, followed by an illustration of GLM data as visualised and applied in early operational trials conducted this spring.
