Comparison of 1 min update GLM .vs. ground-based detection for new updraft tower.

Upper-Left is FED, Upper-Right is 1 min pulse ENTLN and Minimum Flash area, Lower-Left is 1min pulse ENTLN and TOE;  and Lower-Right Average Flash area.  First detected “pulse” is evident about 5 minutes prior to first GLM detections.  Note that the initial pulses in a new updraft may not be associated with a “flash”.    Also note the parallax error in the satellite-based detection.  – Quik Twip
