FED vs GED (Event Density)

Over the course of the week I have been concerned with comparing the consistently low FED values (single digit for most storms) with the other lightning fields including ground-based networks. Visually the low counts per pixel do not grab your attention when looking at a busy scene with storms in a variety of stages of their life cycle. The PIs suggested using Event Density (group extent density) as an alternative with the understanding that it will show higher values. To me the GED compares more nicely with the other GLM products than the FED and also helps in distinguishing core intensity within a storm complex.  It also compares more favorably with the number of events from ENI data for easier transition from one network to another. The example below all shows the striping across Pennsylvania as the pixel sizes are adjusted further away from nader. - SCoulomb
