Technology

Complete EUCLID network consists of about 164 sensors, installed in all Europe countries which contributes to the lightning detection.

All lightning data are detected by electromagnetic sensors, which send raw data to a central analyzer. The analyzer and sensor technology is provided by Vaisala. Each sensor detects the electromagnetic signal emitted by the lightning return stroke. Most common method of lightning detection in modern sensors is the combined method.

This technology uses GPS Satellite signals for time synchronization.

For each lightning stroke the main parameters are recorded, namely the time of event, the impact point (Latitude and longitude), the Current intensity and polarity, and the number of subsequent strokes.

Lightning data from all EUCLID sensors are concentrated in real-time in two EUCLID central operational centers. Communication between sensors and central analyzer is via TCP/IP Protocol. Lightning measured data from sensors are computed in central analyzer immediately to calculate the lightning locations and optimise the data quality. The resulting data are sent in the course of processing to the Euclid service operational center. This leads to a complete picture of lightning activity in real time. All lightning data collected is archived as well for post-storm analysis.
