Analysis of lightning-ionosphere interaction using simultaneous records of source current and 380 km distant electric field

Mario Paolone, Marcos Rubinstein, Mohammad Azadifar, Wolfgang Schulz, Davide Pavanello, Dongshuai Li

We present simultaneous current and wideband electric field waveforms at 380 km associated with upward lightning flashes initiated from the Santis Tower, Switzerland. To the best of our knowledge, the dataset presented in this study includes the first simu ...
