The impact on the ozone layer from NOx produced by terrestrial gamma ray flashes

摘要: The motivation of this work is to understand the effects Terrestrial Gamma-ray Flashes (TGFs) on ozone layer. One main ozone-destroying mechanisms production NOx in stratospheric region. from lightning has been considered as a possible cause depletion but probably little transported tropopause stratosphere. Since energetic particles TGFs travel ≈ 12 km space, resulting ionization can produce directly In order quantify TGFs, we use Runaway Electron Avalanche Model (REAM) simulate typical setup acceleration region inside thundercloud. photons are then through Earth's atmosphere, where they deposit some their energy We calculate number molecules produced by considering average required one electron-ion pair. Finally effect TGF estimated using global annual rate TGFs. It that completely negligible compared other sources, and therefore have no
