GLM vs Ground Network Lightning Detection

Convection beginning to fire off along remnant outflow boundary from earlier storms across northern Iowa. Monitoring the GLM lightning data and the cloud to ground sensor networks to see we there would be an appreciable time difference between the first cloud flashes observed versus the first cloud to ground strikes. GLM first picked up cloud flashes around 2019Z in Hancock County while the first appreciable CG strikes occurred around 2040Z. GLM shows to be beneficial in highlighting areas of convective initiation before cloud to ground sensors.
