IC Stroke Rate Counter
The IC stroke rate counter, shown with and without an alert bar.
Default yellow alert trigger level: 50
Default red alert trigger level: 250
Record kept: Yes
The IC stroke rate counter shows the number of IC
(intercloud/intracloud)
strokes that have been
detected in the last minute. CID (compact intercloud
discharge) strokes are included in this total.
IC strokes are more easily detected from storms that
are relatively nearby (within 150 km or 250 miles).
A new record value is denoted by swapping the colors
of the counter and its background.
This counter is not used with the LD-250.

of +IC (positive intercloud/intracloud) strokes that
have been detected in the last minute.
