NAMMA LIGHTNING ZEUS DATA V1

The NAMMA Lightning ZEUS data is provided by World-ZEUS Long Range Lightning Monitoring Network Data obtained from radio atmospheric signals located at thirteen ground stations spread across the European and African continents and Brazil from August 1, 2006 to October 1, 2006. Lightning activity occurring over a large part of the globe is continuously monitored at varying spatial accuracy (e.g. 10-20 km within and >50 km outside the network periphery) and high temporal (1 msec) resolution. Time is determined by the Arrival Time Difference between the time series from the pairs of the receivers. These data files were generated during support of the NASA African Monsoon Multidisciplinary Analyses (NAMMA) campaign, a field research investigation sponsored by the Science Mission Directorate of the National Aeronautics and Space Administration (NASA). This mission was based in the Cape Verde Islands, 350 miles off the coast of Senegal in west Africa. Commencing in August 2006, NASA scientists employed surface observation networks and aircraft to characterize the evolution and structure of African Easterly Waves (AEWs) and Mesoscale Convective Systems over continental western Africa, and their associated impacts on regional water and energy budgets.

NAMMA 雷电 ZEUS 数据集由世界 ZEUS 长程雷电监测网络数据提供，该数据源自分布于欧洲、非洲大陆及巴西的十三处地面站所采集的无线电大气信号，时间跨度为 2006 年 8 月 1 日至 2006 年 10 月 1 日。对全球大部分地区的雷电活动进行持续监测，空间精度各异（例如，网络边缘内为 10-20 公里，边缘外超过 50 公里），时间分辨率极高（1 毫秒）。时间通过接收器对时间序列的到达时间差来确定。这些数据文件是在支持美国国家航空航天局（NASA）非洲季风多学科分析（NAMMA）任务期间生成的，该任务是一项由美国国家航空航天局（NASA）科学任务局赞助的实地研究调查。该任务以佛得角群岛为基地，位于西非塞内加尔海岸 350 英里处。自 2006 年 8 月开始，NASA 科学家利用地表观测网络和飞机，对西非大陆上的非洲东风波（AEWs）和尺度对流系统（MESOSCALE CONVECTIVE SYSTEMS）的演化和结构进行表征，并研究它们对区域水资源和能源预算的影响。
