SPARC SOLARIS-HEPPA Working Group Meeting 11-12 June 2020, Bergen/Norway

SPARC SOLARIS-HEPPA Working Group Meeting 16-17 June 2022, Bergen/Norway

The meeting will finally happen - in person - in June 2022, see for details.


The meeting focuses on (but is not limited to) the following topics

  • Solar forcing by solar irradiance variability and energetic particle precipitation, including direct chemical impacts. A special focus will be given to efforts towards solar forcing recommendations for CMIP7. This topic includes also intercomparisons of modeled and observed chemical responses to electron precipitation in the mesosphere and lower thermosphere (HEPPA-4).
  • Coupling mechanisms and processes responsible for solar signal transfer in the atmosphere
  • Solar surface climate impact and decadal predictability
  • Methodological analysis and assessment of existing statistical approaches to analyze solar signals in model and observational data

For this meeting, only invited and contributed oral presentations are planned (i.e., no poster presentations). Sufficient time will be allocated for discussions on individual WG results as well as for a general discussion on SOLARIS-HEPPA research.

Limited funds for travel support for early career scientists (PhD students and Postdocs within 4 years after your PhD) have been made available by SPARC/WRCP. Please let us know as soon as possible (no later than 1 May 2022) if you would like to apply for support (by sending an email to Hilde.Nesse at and preferably in cc to bernd at and kmatthes at


The meeting will take place  on 16 - 17 June 2022 in Bergen (Norway) at the Department of Physics and Technology (Allégaten 55, 5007 Bergen). For more info about the Bergen you may start with
