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 involved in a NOAA experiment using total lightning data, and I think it will be a real game changer.
The data below is still test data, but the good news here is that we know the GLM is working!!
