About is worldwide, real time, community collaborative lightning location network.

The aim of the project is to accomplish a low budget but high accurate world-wide lightning location network based on a high number of receiver sites spaced close to each other, typically separated by 50 km - 250 km. Those stations transmit their data to a central server, where the stroke locations are computed by the arrival times of the signals. The station operators are volunteers who bought and assembled the hardware by themselves. There are also volunteer programmers who develop and/or implement algorithms for the location or visualization of sferic positions, and people who assist anyway to keep the system running. There is no restriction on membership. There is no fee and no contract. If a receiver site stops pooling its data for a longer time period, the server stops providing the access to the archive of sferic positions for the corresponding user. The sferic positions are free accessible in raw format to those participants whose stations transmit their data to our server. The station owner can use the raw data for all non-commercial purposes. The lightning activity is additionally displayed on several public maps like or Light- Most of the maps can be used for non-commercial purposes. This wiki gives an overview about the physical and technical background of our lightning detection and locating technology. It is also an assembling and operation manual for participants.
