CGLSS
Cloud-to-Ground Lightning Surveillance System

The Cloud-to-Ground Lightning Surveillance System (CGLSS) is a ground-based lightning detection network at Kennedy Space Center, operated by the United States Air Force. It comprises six medium-gain IMPACT Enhanced Sensitivity and Performance (ESP) sensors developed by Vaisala. The CGLSS network detects cloud-to-ground lightning by capturing electromagnetic waveforms of the return stroke, transmits the data to a central processor that estimates the stroke's intensity and location, and delivers this information to users in real time. Lightning data from the network supports decisions about ground and launch activities along the Florida coast.
