The Fly’s Eye GLM Simulator (FEGS) is a multi-band radiometer system designed to measure lightning optical emission through thunderstorm cloud-tops. It is carried as a payload on the NASA ER-2 high-altitude aircraft with a primary objective to provide ground validation measurements for the Geostationary Lightning Mapper onboard NOAA GOES-R series satellites. During 2022/23 a series of upgrades were applied to the FEGS optical and electronics systems to improve radiometric precision and optimize the sensor dynamic range. In July 2023 FEGS will collect a new set of observations as part of the Airborne Lightning Observatory for FEGS and Terrestrial Gamma-Ray Flashes (ALOFT) flight campaign. This presentation will describe recent upgrades to the FEGS instrument, provide a preliminary analysis of observations from the ALOFT campaign, and discuss implications for future space-based lightning optical detectors.
