科尔多巴阿根廷马克思仪表阵列(CAMMA)由10个第二代亨茨维尔阿拉巴马州马克思仪表阵列(HAMMA 2)传感器组成，在2018年底的自适应地面观测(Relampago)实地活动期间，在阿根廷科尔多瓦运行，对带电、闪电和中/微尺度过程进行遥感。从活动中获得的初步结果表明，新的传感器能够比第一代传感器提供更详细的各种闪电过程的描述。比较了CAMMA和共址闪电映射阵列(LMA)对闪电的映射。对于大多数闪光，CAMMA和LMA绘制的整体闪光结构看起来相似。然而，在较小的时间尺度上的比较表明，大多数CAMMA和LMA源不是同时存在的，这表明不匹配的源可能是由于主导不同频率的引导者传播的不同物理过程以及数据处理和定位技术的差异。
The Córdoba Argentina Marx Meter Array (CAMMA), consisting of 10 second‐generation Huntsville Alabama Marx Meter Array (HAMMA 2) sensors, operated at Córdoba, Argentina, during the Remote sensing of Electrification, Lightning, And Mesoscale/microscale Processes with Adaptive Ground Observations (RELAMPAGO) field campaign in late 2018. Initial results obtained from the campaign demonstrate that the new sensor is able to provide a significantly more detailed depiction of various lightning processes than its first generation. The lightning flashes mapped by the CAMMA and a colocated Lightning Mapping Array (LMA) were compared. The overall flash structures mapped by the CAMMA and the LMA look similar for most of the flashes. However, comparisons at smaller time scale show that the majority of CAMMA and LMA sources are not concurrent, indicating that unmatched sources were possibly due to different physical processes in leader propagation dominating different frequencies and differences in data processing and location techniques.
