The Fly’s Eye GLM Simulator (FEGS) is an airborne radiometer designed to calibrate and validate the Geostationary Lightning Mapper (GLM) on the GOES-16 satellite. It features a 5 x 5 array of radiometers that measure the optical radiance of lightning at 777.4 nm, along with five additional spectral channels at 337, 400, 500, 660, and 675 nm. FEGS provides a spatial resolution of 2 x 2 km and a temporal resolution of 10 μs.
