It’s called the Geostationary Lightning Mapper (GLM for short), and while we have been seeing some real time images from GOES-16 for over a month now, the GLM is still being checked out.

Current lightning data sees cloud to ground strokes, but these coordinate poorly with severe weather. Research shows that total lightning does correlate well with severe weather and can significantly increase lead times and it will likely reduce false alarms as well. I was …
