Whitepaper #019 in the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033. Main topics: space weather applications. Additional topics: space weather research/applications/operations pipeline; ground-based missions/projects.
The opinion of the technical community is that there are not enough magnetometers in the CONUS to properly inform GIC hazard analyses and industry reliability standards (e.g. NERC TPL-007).
