NAMMA ATD LIGHTNING DATA V1

The NAMMA ATD Lightning data provided by the UK Meterological Office from multiple outstations contains lightning stroke data, latitude and longitude, accuracy and weighting for fading-in flashes of lightning for the African Coast during the NAMMA experiment. Time is determined by the Arrival Time Difference (ATD) of the reporting stations. 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.

英国气象办公室提供的NAMMA ATD闪电数据，由多个观测站收集，包括闪电击中数据、纬度和经度、精确度和闪电渐隐的权重，这些数据记录了非洲海岸在NAMMA实验期间的情况。时间由报告站的到达时间差（ATD）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）行动计划期间生成的，该行动计划是一项由NASA科学任务局资助的现场研究调查。该任务位于西非塞内加尔海岸350英里外的佛得角群岛。自2006年8月开始，NASA科学家利用地表观测网络和飞机，对西非大陆上空非洲东风波（AEWs）和中尺度对流系统（MCS）的演变和结构进行了表征，并研究了它们对区域水循环和能量收支的影响。
