CAMEX-4 DC-8 LIGHTNING INSTRUMENT PACKAGE (LIP) V1

The CAMEX-4 DC-8 Lightning Instrument Package (LIP) dataset was collected by the ER-2 Lightning Instrument Package (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 during the CAMEX-4 campaign. 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 项目中的 DC-8 雷电仪器包（LIP）数据集，由 ER-2 雷电仪器包（LIP）采集而成，该仪器包能够轻易获取电场矢量分量（即，Ex、Ey、Ez），从而极大地提升了我们对在 CAMEX-4 期间飞越的雷暴电结构的认知。场强计能够测量从晴好天气电场（即，数伏至数十伏每米）到更大雷暴场（即，数十千伏每米）范围内的电场分量。通过数据中电场变化的突然性，可以识别出总闪电（即，云地闪电、云内闪电）。导电性探头用于测量飞机飞行高度处的空气导电性。利用电场和空气导电性测量值，可以推导出风暴电电流。
