Miriam Sinnhuber (Karlsruhe Institute of Technology, Germany) Atmospheric impact of space weather: From observations to CMIP7 recommendations

Miriam Sinnhuber (Karlsruhe Institute of Technology, Germany) will deliver a talk on the topic "Atmospheric impact of space weather: From observations to CMIP7 recommendations".

Abstract:

Space weather events often are accompanied by precipitation of energetic particles from the magnetosphere or the solar wind into the atmosphere. Energetic particle precipitation can lead to significant changes in the composition of the mesosphere and lower thermosphere, initiating composition-radiative-dynamical feedbacks with implications for atmospheric dynamics potentially down to the troposphere. Consequently, atmospheric ionization by energetic particle precipitation is recommended as part of the solar forcing for coordinated chemistry-climate experiments like, e.g., the upcoming CMIP7 experiments. 

Here, a short overview will be given about observations of space weather impacts on atmospheric composition and of the underlying processes, as well as a summary of the new solar forcing recommendations for CMIP7.
