Reality Vs. Simulation
Comparing what we see to what models can simulate
Interhemispheric asymmetries require broad system level understanding and CUSIA’s Capabilities Assessment Matrix (CAM ) enables us to do so. The CAM compares a range of scientific observations to modeling capabilities of current state-of-the-art global and coupled models (none of which can properly account for Earth’s interhemispheric asymmetries). Mapping our current understanding and modeling capabilities of interhemispheric asymmetries, the CAM provides our community the ability to quickly and confidently identify, prioritize, and pivot our efforts to address our most pressing scientific questions.
IMF By Component
Intrinsic Source of Asymmetry
Relative Importance of Asymmetry – Primary
Causes: Dipole Tilt, IMF By
Modeling Capability:
All global MHD models can include IMF By in the solar wind time series that drive the code. Many aspects of asymmetry produced by IMF By, such as shear in the Birkeland current patterns and asymmetric potential distributions, are captured to some extent by the global codes. However, inner magnetosphere codes that depend on the polar ionosphere current use only the northern hemisphere solution.
