A low frequency 3D lightning mapping network in north China

Abstract A 3D low-frequency lightning mapping network with eight stations is deployed in the SHAndong Triggering Lightning Experiment (SHATLE) in north China. The ABA (A, B double time base) data acquisition system based on first input first output memory is adopted. The effective and stable acquisition of electromagnetic radiation data from lightning is realized by designing real-time monitoring of the acquisition speed. The accuracy of the time of the data is ensured using a double timestamp scheme. Noise pulse analysis is integrated to effectively solve the adverse effects of the background noise during the 3D location of the lightning radiation sources. According to the error distribution obtained by Monte Carlo estimation, the horizontal location errors are
