Blitzortung is a lightning detection network for the location of electromagnetic discharges in the atmosphere (lightning discharges) based on the time of arrival (TOA) and time of group arrival (TOGA) method. It consists of several lightning receivers and one central processing server. WB9KMW is a participating station.
Useful performance statistics for North America can be found at LightningMaps. I monitor my VLF lightning detection & reporting system through a local Controller screen from my QTH.
An Acu-Rite weather station is mounted on my house roof. It continuosly transmits weather data to a diplay unit in my ham shack. In addition, a receiver is connected to the Internet and data is ported to my Acu-Rite web site, and from there it is relayed to the WunderMap displayed above.
