Abstract
This perspective advocates for the need of a combined system science approach to global magnetospheric models and to spacecraft magnetospheric data to answer the question “Do simulations behave in the same manner as the magnetosphere does?” (instead of the standard validation question “How well do simulations reproduce spacecraft data?”). This approach will 1) validate global magnetospheric models statistically, without the need for a direct comparison against spacecraft data, 2) expose the deficiencies of the models, and 3) provide physics support to the system analysis performed on the magnetospheric system.
Highlights
The Helio2050 workshop was organized in May 2021 to develop a vision for Heliophysics for the 30 years
Earlier works focused on applying global MHD codes to specific event challenges (Raeder et al, 1997; Ridley et al, 2002), which led to community-wide event challenges to assess the performance of different codes against observational data
We point out the need to apply system science tools to global magnetospheric models to understand if the system behavior of the global models is the same as the system behavior of the real magnetosphere and to overcome the limitations described above
Summary
The Helio2050 workshop was organized in May 2021 to develop a vision for Heliophysics (the Sun, the solar wind, and planetary magnetospheres and ionospheres) for the 30 years. Earlier works focused on applying global MHD codes to specific event challenges (Raeder et al, 1997; Ridley et al, 2002), which led to community-wide event challenges to assess the performance of different codes against observational data (see for instance Pulkkinen et al, 2013) This type of study is very useful in identifying the general trends of different models, in providing physics support and understanding magnetospheric reactions, and in providing comparisons with other codes.
