Atmosphere-Ionosphere coupling: atmospheric electricity (TLEs, TGFs, lightning) and the upper atmosphere physics and chemistry


Scientific rationale

The goal of the workshop "Atmosphere-Ionosphere coupling: atmospheric electricity (TLEs, TGFs, lightning) and the upper atmosphere physics and chemistry" is to initiate the discussion between the various scientific communities working on this subject.

Since their discovery beginning of 90's there have been many observations of impressive electric discharges and energetic bursts of gamma-radiation above thunderstorms. The late discovery of these phenomena demonstrates that our understanding of thunderstorms and of processes in the atmosphere above them is limited. They further underscore the point that thunderstorms affect not only the troposphere but all atmospheric layers to the near-Earth space, and that several research fields must combine to advance our knowledge of the effects of thunderstorms on the atmosphere-ionosphere system.

The scientific communities interested are the ones working on:

The goal is to gather within a GdR the various French teams involved. This GdR would be the ideal place to define scientific priorities; to promote the development of theory, modelling, and new experiments; and to coordinate preparatory research activities in the frame of the CNES satellite project TARANIS, and campaigns of ground, aircraft and balloon based measurements.
