人工引雷通道底部电流测量数据集（2014-2018）

同自然闪电的测量相比，人工引雷实验的一大优势在于其可在指定地点，既定时间测量闪电通道上的电流强度及其时间变化波形，可以直观的判断闪电的放电极性和时间尺度。可研究的典型闪电放电过程包括初始电流脉冲（同闪电先导的初始发展过程有关），初始连续电流和回击电流等，以及人工引雷中特有的先驱脉冲电流。Compared with measurements of natural lightning, a major advantage of triggered lightning experiments is that they can measure the current intensity and its time-varying waveform along the lightning channel at designated locations and predetermined times, allowing for straightforward determination of the discharge polarity and temporal scale of lightning. Typical lightning discharge processes that can be investigated include initial current pulses (related to the initial development of lightning leaders), initial continuous current, return stroke currents, and other relevant processes, as well as precursor pulse currents unique to triggered lightning experiments.
