Looking at Lightning From On High! The GLM Works!
The new GOES-16 weather satellite has something no geostationary weather satellite has ever had before. An instrument that can see lightning. In real time. 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. Today, NASA and Lockheed released some new video of the GLM in action …

First Images from the GOES-16 Lightning Mapper
The Geostationary Lightning Mapper (GLM) is working. This instrument will likely be a revolutionary advance in severe storm forecasting and warnings and can measure the total lightning in storms. 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 …
