Supplementary information

Figure S1:

Swarm B 2014 yearly mean comparing mean binned standard deviation with mean binned dB/dt over 20 s intervals.

Figure S2:

Swarm B 2014 yearly mean comparing mean binned standard deviation over 5 and 10 s intervals.

Figure S3:

Two further examples the icosahedron binning in the same style as Figure 1, main text. The left is a vertex with only 5 neighbours forming a pentagon bin (over the Red Sea for reference). The right shows two separate satellite passes being included in the bin (over South England for reference).

Figure S4:

Swarm B yearly F_s normalized by the active year of 2023 in the same format as Figure 3, main text.

Figure S5:

Swarm B distribution of $σ_{F_{s}}$ ${\sigma }_{{F}_s}$ across the years 2014–2023.

Figure S6:

Hazard variation plots for the 7–8th September 2017 using OPER Swarm B measurements, in the same format as Figure 7, main text, but focusing on the B_x component.

Figure S7:

Hazard variation plots for the 7–8th September 2017 using OPER Swarm B measurements, in the same format as Figure 7, main text, but focusing on the B_y component.

Figure S8:

Hazard variation plots for the 7–8th September 2017 using OPER Swarm B measurements, in the same format as Figure 7, main text, but focusing on the B_z component.

Figure S9:

Hazard variation plots for the 7–8th September 2017 using OPER Swarm B measurements, in the same format as Figure 7, main text, but focusing on the B_v component.
