CAMEX-4 ER-2 LIGHTNING INSTRUMENT PACKAGE (LIP) V1

The CAMEX-4 ER-2 Lightning Instrument Package (LIP) dataset was collected by the ER-2 LIP, which allows the vector components of the electric field (i.e, Ex, Ey, Ez ) to be readily obtained, and thus greatly improves our knowledge of the electrical structure of storms overflown. The field mills measure the components of the electric field over a wide dynamic range extending from fair weather electric fields, (i.e., a few to tens of V/m) to larger thunderstorm fields (i.e., tens of kV/m). Total lightning (i.e., cloud-to-ground, intracloud) is identified from the abrupt electric field changes in the data. The conductivity probe measures the air conductivity at the aircraft flight altitude. Storm electric currents can be derived using the electric field and air conductivity measurements.

CAMEX-4 ER-2 电场仪包（LIP）数据集由ER-2 LIP收集而成，该数据集允许我们轻易获取电场的矢量分量（即Ex、Ey、Ez），从而极大地提升了我们对所飞越风暴电结构的认知。场强计测量了电场在宽广的动态范围内的分量，范围从晴好天气下的电场（即数伏到数十伏每米）至更大的雷暴电场（即数十千伏每米）。通过数据中电场突变的急剧变化，可以识别出总闪电（即云对地、云内）。导电率探头测量了飞机飞行高度处的空气导电率。利用电场和空气导电率测量值，可以推导出风暴电电流。
