Hunting Energetic Radiation from Thunderstorms
The true nature and mechanisms of terrestrial gamma-ray flashes (TGFs) have remained mysterious since their discovery in the 1990s. Despite decades of detections, their violent origins and irregularity make them particularly difficult to observe directly. Combined with the wide range of measured characteristics, this has kept the details of these energetic events in the dark. The recent ALOFT (Airborne Lightning Observatory for FEGS and TGFs) campaign has undertaken the challenge of hunting these elusive flashes from an airborne platform. This was performed by the NASA ER-2 aircraft in July 2023 equipped with a host of meteorological, electric field, and gamma-ray instruments to study intense tropical thunderstorms and their connection to gamma-ray production. Here we present on the campaign's success alongside some of its exciting preliminary results.
