Lightning driven inner radiation belt energy deposition into the atmosphere: regional and global estimates
International audience In this study we examine energetic electron precipitation fluxes driven by lightning, in order to determine the global distribution of energy deposited into the middle atmosphere. Previous studies using lightning-driven precipitation burst rates have estimated losses from the...
