CAMEX-3 LIGHTNING INSTRUMENT PACKAGE (LIP) V1

The CAMEX-3 Lightning Instrument Package (LIP) dataset contains electrical field measurements of lightning within storms studied during the Convection And Moisture EXperiment 3 (CAMEX-3). The LIP was flown aboard the NASA ER-2 aircraft, enabling vector components of the electric field (i.e, Ex, Ey, Ez) to be readily obtained, thus greatly improving knowledge of the electrical structure within storms overflown. Measurements within this dataset include field mill data, conductivity probe temperatures from two probes, and navigation data. 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-3闪电测量设备包（LIP）数据集收录了在对流与湿度实验3（CAMEX-3）期间对风暴中闪电的电场测量数据。LIP设备被搭载于NASA的ER-2飞机上，使得电场矢量分量（即Ex、Ey、Ez）能够轻易获得，从而极大地提升了对于所经风暴电结构的认知。该数据集包含场强仪数据、两个探针的导电率探针温度以及导航数据。场强仪测量了从晴好天气电场（即几到数十伏每米）到更大雷暴电场（即数十千伏每米）的广泛动态范围内的电场分量。通过数据中的电场突变识别出总闪电（即云对地、云内闪电）。导电率探针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。
