Untangling the solar wind and magnetospheric drivers of the radiation belt electrons

S Wing, JR Johnson, DL Turner… - Journal of …, 2022 - Wiley Online Library
Many solar wind parameters correlate with one another, which complicates the causal‐effect
studies of solar wind driving of the magnetosphere. Conditional mutual information (CMI) is …

Causal inference in the outer radiation belt: Evidence for local acceleration

P Manshour, C Papadimitriou… - Geophysical …, 2024 - Wiley Online Library
Currently, there is no clear understanding of the comprehensive set of variables that controls
fluxes of relativistic electrons within the outer radiation belt. Herein, the methodology based …

Evaluating ecohydrological model sensitivity to input variability with an information-theory-based approach

MA Farahani, A Vahid, AE Goodwell - Entropy, 2022 - mdpi.com
Ecohydrological models vary in their sensitivity to forcing data and use available information
to different extents. We focus on the impact of forcing precision on ecohydrological model …

Complexity Heliophysics: A lived and living history of systems and complexity science in Heliophysics

RM McGranaghan - Space Science Reviews, 2024 - Springer
This review examines complexity science in the context of Heliophysics, describing it not as
a discipline, but as a paradigm. In the context of Heliophysics, complexity science is the …

A comparison of two causal methods in the context of climate analyses

D Docquier, G Di Capua, RV Donner… - Nonlinear Processes …, 2024 - npg.copernicus.org
Correlation does not necessarily imply causation, and this is why causal methods have been
developed to try to disentangle true causal links from spurious relationships. In our study, we …

Further investigation of the effect of upstream solar-wind fluctuations on solar-wind/magnetosphere coupling: Is the effect real?

JE Borovsky - Frontiers in Astronomy and Space Sciences, 2023 - frontiersin.org
There is a general consensus that fluctuations in the solar wind magnetic field and/or the
Alfvenicity of the solar wind drive a solar wind-magnetosphere interaction. 11 years of hourly …
