A couple of times this week we have noticed in comparison with ENI, missed flashes on GLM. The first flash is typically the most important for IDSS for outdoor venues, especially since the need for lead time grows with increased size of crowds. In order to get the most lead time there likely needs to be a trade-off with higher false detections for GLM to keep up with ground-based networks for the weaker events. It is preferred that GLM has equal or better detection capability for low energy and first flash as the ground-based networks in order for it to be trusted for application in IDSS. The more times flashes are depicted by other sources and not by GLM the less GLM is going to be trusted in a forecast environment despite its other benefits. Similarly the more ECMWF data shows a faster fropa with arctic outbreaks the less the GFS is going to be used to time shallow fronts.
