Ground-based magnetometers used to measure magnetic fields on the Earth’s surface (B) are central to Heliophysics research. We summarize present magnetometer infrastructure, describe research needed to improve our understanding of the causes and consequences of B, and describe infrastructure and policies needed to support this research and related space weather models.
