FEGS

FEGS is an airborne radiometer system designed to provide cal/val measurements for GLM from high altitude aircraft. It consists of a 5 x 5 array of radiometers each with a narrow passband filter to isolate the 777.4 nm neutral oxygen emission triplet radiated by lightning. The radiometers will measure the optical radiance emitted by lightning that is transmitted through the cloud top with a temporal resolution of 10 μs. When integrated on the NASA ER-2 aircraft, the FEGS array with its 90° field-of-view will observe a cloud top area nearly equal to a single GLM pixel. This design will allow FEGS to determine the temporal and spatial variation of light that contributes to a GLM event detection.
