10 second updated sample waveform received by the Clifton VA Blitzortung.org lightning detection station.
Data is supplied by Blitzortung network members, including the Clifton VA station to the network using their home-built Blitzortung hardware.
The (Red) station monitors H-field shown in orthagonal directions in red(NNW-SSE) and green(WSW-ENE),
 |
as well as E-field, which is shown in violet (18 KHz Low Pass Filter), aqua (44 KHz Low Pass Filter) and orange (50 KHz Low Pass Filter).
The (Blue) station monitors H-fields with 3 antennas in a Delta configuration red , green and
yellow( as well as in E-field which is shown in violet.
Signals such as these are sent to a set of servers in Europe to correlate the Time-Of-Arrival at detectors v.s. GPS-time and the network uses that to locate strikes. There is a great (and somewhat hypnotic) realtime map for North America where you can see real-time strike info, and which stations participated in the location of that strike. There is a companion site that offers the same data and uses a zoomable Google Map for display.
For those interested in more information about Blitzortung, there is a Blitzortung forum in the US at WXForum.net.
