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年地中海海域范围内的多源观测数据，涵盖冬季（DJF，即12月、1月、2月）闪电事件（含发生时间、空间位置与强度）、太阳活动（太阳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（Convective Available Potential Energy）、海表水温、盐度、pH值及总碱度。两个CSV文件对应原始WWLLN（世界闪电定位网络，World Wide Lightning Location Network）数据集经筛选后的两类能量等级划分结果，分别为<0.1兆焦（MJ）与>0.5兆焦（MJ）。此外，还包含本研究周期内地中海海域冬季（DJF）闪电闪光密度与降水的核密度估计（Kernel Density Estimation, KDE）可视化图。
