Asfur et al Mediterranean Sea lightning data analysis tables and graphs

Combined datasets of wintertime (DJF) lightning events (time, location and intensity), solar activity (sunspot activity and total solar irradiance), total electron content in the ionosphere, convective available potential energy, sea surface seawater temperature, salinity, pH and total alkalinity during the period 2009-2019 that occurred within the water boundaries of the Mediterranean Sea. The two CSV files correspond to the division of the original WWLLN dataset after filtering into two energy categories, <0.1 MJ and >0.5 MJ. In addition, KDE figures for wintertime (DJF) lightning flash density and precipitation over the Mediterranean Sea throughout the study period.

本数据集整合了2009-2019年间地中海海域内发生的冬季（12月-1月-2月，DJF）闪电事件（含发生时间、空间位置与强度）、太阳活动（黑子活动与总太阳辐照度）、电离层总电子含量、对流有效位能、海表水温、盐度、pH值及总碱度数据。数据集包含两个CSV文件，对应经筛选后的原始世界闪电定位网络（World Wide Lightning Location Network, WWLLN）数据集按能量划分为<0.1兆焦与>0.5兆焦两个类别后的子集。此外，本数据集还涵盖研究周期内地中海海域冬季（DJF）闪电闪光密度与降水量的核密度估计（Kernel Density Estimation, KDE）可视化图件。
