Sitting on the beach looking west almost nightly, you can see cloud to cloud lightning Which could be very far because there is no sound But on the map, even 500 miles away there are no hits. Furthermore, almost daily there is cloud to ground strikes with no hit.
(Yesterday, 04:46)GeezerD Wrote: As I understand it (I have gotten a detector just this year) Cloud to Cloud lightning (IC, Intra-Cloud) has a couple of characteristics that make it harder for the Blitzortung network to detect or locate.
First is the polarization of the transmission: the antennas used are best at vertically polarized signals, and CG (Cloud-Ground) strike are what transmit most efficiently vertically polarized. These CG strikes also have the most efficient ground-wave propagation.
I'm unfamiliar with the algorithm that is used to identify particular strikes at multiple stations, but I suspect lightning transmission signatures are more directionally invariant with CG strikes than IC strikes.
South America and Africa have really low location rates as well, considering how well represented they are with other lightning detection networks. Blitzortung seems very biased towards northern and and western hemisphere detections.

The ANSWER is quite simple, actually:
...and about a dozen DOA...
