Stroke count

Here you can see the whole stroke count per hours detected by the lightning network, the count of detected strokes/h of the station Boulder and the mean stroke count for all stations

Graphs: Stroke statistics

Signal count

The count of received signals per hour of the station Boulder and also mean value of all stations.

Graphs: Signal statistics


Stroke and locating ratios are important parameters for the correct adjustment of the station. Calculations:
locating ratio = (detected strokes of the station) / (signals of the station)
stroke ratio = (detected strokes of the station) / (network stroke count)
