Title: POLL:Is RED (PCB 10.3) outperforming GREEN (PCB 6.8 ) in Lightning Detection?
Post by: schwab on August 11, 2013, 09:24:35 AM

Is the new RED (PCB 10.3) currently outperforming the older legacy GREEN (PCB 6.8 ) in Blitzortung Network Lightning Detection?

One measure of many is this Efficiency Data:

I'll give that a "Yes, but" answer. I have the 1m loops on RED. For my case, it is kind of an apples-and-oranges comparison.
It could be because of the antennas rather than anything to do with RED.

There also tends to be more false strikes.

What is a "false strike"?

If a strike is detected, it means it is coordinated with >= 5 other stations (Red or not), so should never be "false".

Or does this mean there are more received signals at a station that do not end up being correlated with other stations and counted as strikes? These are not necessarily false strike detections. They could be valid lightning detections that are not able to be correlated with the minimum number of other station. It could mean your station is receiving better than other stations.

I'm referring to strikes reported when there is no weather to support there being a strike anywhere in the vicinity or region (e.g. clear skies).

Such signals cannot be distinguished from distant strike detections which are uncorrelated with other stations. I believe this is a frequent occurrence, especially in the US with low station density.
