Abstract :
The results of measurements of lightning quantities at MCS are updated. Simultaneous records of current, electric field, optical sensor data and high-speed video of some events are considered in the analysis presented in this work. The main parameters of the lightning currents are summarized. Two sets of interesting and rare results consisting of first return stroke M-events and upward lightning currents measured in tropical regions are addressed and their main features are discussed.
