UNR - Comparison of GLM & ENTLN lightning data

2015Z: I noticed rather low values of GLM flash extent density & total energy with a severe warned storm near Wheatland in eastern WY so out of curiosity I decided to plot observed CG & cloud flashes from the ENTLN. Despite low values of Flash extent density & total energy the earth based network observed a rather active storm with numerous CG flashes & even more cloud flashes. The total energy product seemed to perform better than flash extent density in conveying the lightning activity in the storm & potential strength of the storm, but if I was only using GLM in a vacuum I likely would have greatly underestimated the potential of this storm. It is becoming more evident to me that the GLM output can differ drastically for "severe" storms depending on the environment, geographic region, & even from storm to storm during the same event.
