This forum supports Geostationary Lightning Mapper (GLM) implementation and training.  The page provides a vehicle for learning about the GLM capabilities and limitations, exploring GLM applications, understanding data quality, and addressing GLM inquiries.

The first Geostationary Lightning Mapper (GLM) launched into orbit aboard the first Geostationary Operational Environmental Satellite R-series (GOES-R), becoming GOES-16 after reaching geostationary orbit on 29 November 2016. The GLM on GOES-16 is the first of four instruments that will provide lightning mapping over most of the western hemisphere through 2036.

The GLM performance meets or exceeds all program specifications, but the data quality will continue to improve.  Simultaneous development and implementation efforts aim to improve the operational utility of the GLM data. New visualizations have been developed for the NWS Advanced Weather Interactive Processing System (AWIPS) software.
