Fredagskollokvium: Nikolai Østgaard: Terrestrial gamma ray flashes, the most energetic photon phenomenon in our atmosphere.

Professor Nikolai Østgaard, Professor at Dept. of Physics and Technology, University of Bergen

Terrestrial gamma ray flashes are the most energetic photon phenomenon (>40 MeV) produced naturally on Earth. This phenomenon that was unknown to mankind before 1991, is produced in thunderstorms, but we do not know how exactly they are produced, how common they are or how they may affect atmospheric chemistry. This seminar will give an introduction and state of our knowledge about this exotic phenomenon.
