Honolulu case
We complete this survey with two cases where the selected station is at
higher magnetic latitude than so far. Figure 12 shows the Honolulu case.
The bulk of Honolulu’s detections are for strokes whose predicted
logarithmic reference transmission (to Honolulu) > -2.5
(Figure 12g), with a low tail out to -4, as had been the case with
Atuona. For the nighttime cohort of strokes (Figures 12d,e), Honolulu
detects very few strokes in South America, whilst its more distant
detections on the West go all the way across India. The Honolulu
patterns of detection/non-detection are grossly consistent with the
model predictions (Figures 12c,f,g).
